+ * << General scanline function procedures >>
+ *  1. bilinear interpolate source pixels
+ *  2. load mask pixels
+ *  3. load destination pixels
+ *  4. duplicate mask to fill whole register
+ *  5. interleave source & destination pixels
+ *  6. apply mask to source pixels
+ *  7. combine source & destination pixels
+ *  8, Deinterleave final result

+ *
+ * All registers with single number (i.e. src0, tmp0) are 64-bits registers.
+ * Registers with double numbers(src01, dst01) are 128-bits registers.
+ * All temp registers can be used freely outside the code block.
+ * Assume that symbol(register .req) OUT and MASK are defined at caller of these macro blocks.
+ *
+ * Remarks
+ *  There can be lots of pipeline stalls inside code block and between code blocks.
+ *  Further optimizations will be done by new macro templates using head/tail_head/tail scheme.

+ * Implementation of pixman_composite_over_8888_0565_asm_neon
+ *
+ * This function takes a8r8g8b8 source buffer, r5g6b5 destination buffer and
+ * performs OVER compositing operation. Function fast_composite_over_8888_0565
+ * from pixman-fast-path.c does the same in C and can be used as a reference.
+ *
+ * First we need to have some NEON assembly code which can do the actual
+ * operation on the pixels and provide it to the template macro.
+ *
+ * Template macro quite conveniently takes care of emitting all the necessary
+ * code for memory reading and writing (including quite tricky cases of
+ * handling unaligned leading/trailing pixels), so we only need to deal with
+ * the data in NEON registers.
+ *
+ * NEON registers allocation in general is recommented to be the following:
+ * d0,  d1,  d2,  d3  - contain loaded source pixel data
+ * d4,  d5,  d6,  d7  - contain loaded destination pixels (if they are needed)
+ * d24, d25, d26, d27 - contain loading mask pixel data (if mask is used)
+ * d28, d29, d30, d31 - place for storing the result (destination pixels)
+ *
+ * As can be seen above, four 64-bit NEON registers are used for keeping
+ * intermediate pixel data and up to 8 pixels can be processed in one step
+ * for 32bpp formats (16 pixels for 16bpp, 32 pixels for 8bpp).
+ *
+ * This particular function uses the following registers allocation:
+ * d0,  d1,  d2,  d3  - contain loaded source pixel data
+ * d4,  d5            - contain loaded destination pixels (they are needed)
+ * d28, d29           - place for storing the result (destination pixels)
+ */
+
+/*
+ * Step one. We need to have some code to do some arithmetics on pixel data.
+ * This is implemented as a pair of macros: '*_head' and '*_tail'. When used
+ * back-to-back, they take pixel data from {d0, d1, d2, d3} and {d4, d5},
+ * perform all the needed calculations and write the result to {d28, d29}.
+ * The rationale for having two macros and not just one will be explained
+ * later. In practice, any single monolitic function which does the work can
+ * be split into two parts in any arbitrary way without affecting correctness.
+ *
+ * There is one special trick here too. Common template macro can optionally
+ * make our life a bit easier by doing R, G, B, A color components
+ * deinterleaving for 32bpp pixel formats (and this feature is used in
+ * 'pixman_composite_over_8888_0565_asm_neon' function). So it means that
+ * instead of having 8 packed pixels in {d0, d1, d2, d3} registers, we
+ * actually use d0 register for blue channel (a vector of eight 8-bit
+ * values), d1 register for green, d2 for red and d3 for alpha. This
+ * simple conversion can be also done with a few NEON instructions:
+ *
+ * Packed to planar conversion:
+ *  vuzp.8 d0, d1
+ *  vuzp.8 d2, d3
+ *  vuzp.8 d1, d3
+ *  vuzp.8 d0, d2
+ *
+ * Planar to packed conversion:
+ *  vzip.8 d0, d2
+ *  vzip.8 d1, d3
+ *  vzip.8 d2, d3
+ *  vzip.8 d0, d1
+ *
+ * But pixel can be loaded directly in planar format using VLD4.8 NEON
+ * instruction. It is 1 cycle slower than VLD1.32, so this is not always
+ * desirable, that's why deinterleaving is optional.
+ *
+ * But anyway, here is the code:

+/*
+ * OK, now we got almost everything that we need. Using the above two
+ * macros, the work can be done right. But now we want to optimize
+ * it a bit. ARM Cortex-A8 is an in-order core, and benefits really
+ * a lot from good code scheduling and software pipelining.
+ *
+ * Let's construct some code, which will run in the core main loop.
+ * Some pseudo-code of the main loop will look like this:
+ *   head
+ *   while (...) {
+ *     tail
+ *     head
+ *   }
+ *   tail
+ *
+ * It may look a bit weird, but this setup allows to hide instruction
+ * latencies better and also utilize dual-issue capability more
+ * efficiently (make pairs of load-store and ALU instructions).
+ *
+ * So what we need now is a '*_tail_head' macro, which will be used
+ * in the core main loop. A trivial straightforward implementation
+ * of this macro would look like this:
+ *
+ *   pixman_composite_over_8888_0565_process_pixblock_tail
+ *   vst1.16     {d28, d29}, [DST_W, :128]!
+ *   vld1.16     {d4, d5}, [DST_R, :128]!
+ *   vld4.32     {d0, d1, d2, d3}, [SRC]!
+ *   pixman_composite_over_8888_0565_process_pixblock_head
+ *   cache_preload 8, 8
+ *
+ * Now it also got some VLD/VST instructions. We simply can't move from
+ * processing one block of pixels to the other one with just arithmetics.
+ * The previously processed data needs to be written to memory and new
+ * data needs to be fetched. Fortunately, this main loop does not deal
+ * with partial leading/trailing pixels and can load/store a full block
+ * of pixels in a bulk. Additionally, destination buffer is already
+ * 16 bytes aligned here (which is good for performance).
+ *
+ * New things here are DST_R, DST_W, SRC and MASK identifiers. These
+ * are the aliases for ARM registers which are used as pointers for
+ * accessing data. We maintain separate pointers for reading and writing
+ * destination buffer (DST_R and DST_W).
+ *
+ * Another new thing is 'cache_preload' macro. It is used for prefetching
+ * data into CPU L2 cache and improve performance when dealing with large
+ * images which are far larger than cache size. It uses one argument
+ * (actually two, but they need to be the same here) - number of pixels
+ * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some
+ * details about this macro. Moreover, if good performance is needed
+ * the code from this macro needs to be copied into '*_tail_head' macro
+ * and mixed with the rest of code for optimal instructions scheduling.
+ * We are actually doing it below.
+ *
+ * Now after all the explanations, here is the optimized code.
+ * Different instruction streams (originaling from '*_head', '*_tail'
+ * and 'cache_preload' macro) use different indentation levels for
+ * better readability. Actually taking the code from one of these
+ * indentation levels and ignoring a few VLD/VST instructions would
+ * result in exactly the code from '*_head', '*_tail' or 'cache_preload'
+ * macro!

+ * Any combinations of source, destination and mask images with 8bpp,
+ * 16bpp, 24bpp, 32bpp color formats are supported.

+ *  - doing most of the work related to L2 cache preload
+ *  - encourages the use of software pipelining for better instructions
+ *    scheduling
+ *
+ * The user of this macro has to provide some configuration parameters
+ * (bit depths for the images, prefetch distance, etc.) and a set of
+ * macros, which should implement basic code chunks responsible for
+ * pixels processing. See 'pixman-arm-neon-asm.S' file for the usage
+ * examples.

+ * This is a macro for implementing cache preload. The main idea is that
+ * cache preload logic is mostly independent from the rest of pixels
+ * processing code. It starts at the top left pixel and moves forward
+ * across pixels and can jump across scanlines. Prefetch distance is
+ * handled in an 'incremental' way: it starts from 0 and advances to the
+ * optimal distance over time. After reaching optimal prefetch distance,
+ * it is kept constant. There are some checks which prevent prefetching
+ * unneeded pixel lines below the image (but it still can prefetch a bit
+ * more data on the right side of the image - not a big issue and may
+ * be actually helpful when rendering text glyphs). Additional trick is
+ * the use of LDR instruction for prefetch instead of PLD when moving to
+ * the next line, the point is that we have a high chance of getting TLB
+ * miss in this case, and PLD would be useless.
+ *
+ * This sounds like it may introduce a noticeable overhead (when working with
+ * fully cached data). But in reality, due to having a separate pipeline and
+ * instruction queue for NEON unit in ARM Cortex-A8, normal ARM code can
+ * execute simultaneously with NEON and be completely shadowed by it. Thus
+ * we get no performance overhead at all (*). This looks like a very nice
+ * feature of Cortex-A8, if used wisely. We don't have a hardware prefetcher,
+ * but still can implement some rather advanced prefetch logic in sofware
+ * for almost zero cost!
+ *
+ * (*) The overhead of the prefetcher is visible when running some trivial
+ * pixels processing like simple copy. Anyway, having prefetch is a must
+ * when working with the graphics data.

+ * Because the alignment of pixel data to cachelines, and even the number of
+ * cachelines per row can vary from row to row, and because of the need to
+ * preload each scanline once and only once, this prefetch strategy treats
+ * each row of pixels independently. When a pixel row is long enough, there
+ * are three distinct phases of prefetch:
+ * * an inner loop section, where each time a cacheline of data is
+ *    processed, another cacheline is preloaded (the exact distance ahead is
+ *    determined empirically using profiling results from lowlevel-blt-bench)
+ * * a leading section, where enough cachelines are preloaded to ensure no
+ *    cachelines escape being preloaded when the inner loop starts
+ * * a trailing section, where a limited number (0 or more) of cachelines
+ *    are preloaded to deal with data (if any) that hangs off the end of the
+ *    last iteration of the inner loop, plus any trailing bytes that were not
+ *    enough to make up one whole iteration of the inner loop
+ * 
+ * There are (in general) three distinct code paths, selected between
+ * depending upon how long the pixel row is. If it is long enough that there
+ * is at least one iteration of the inner loop (as described above) then
+ * this is described as the "wide" case. If it is shorter than that, but
+ * there are still enough bytes output that there is at least one 16-byte-
+ * long, 16-byte-aligned write to the destination (the optimum type of
+ * write), then this is the "medium" case. If it is not even this long, then
+ * this is the "narrow" case, and there is no attempt to align writes to
+ * 16-byte boundaries. In the "medium" and "narrow" cases, all the
+ * cachelines containing data from the pixel row are prefetched up-front.

+ * PDF blend modes:
+ *
+ * The following blend modes have been taken from the PDF ISO 32000
+ * specification, which at this point in time is available from
+ * http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf
+ * The relevant chapters are 11.3.5 and 11.3.6.
+ * The formula for computing the final pixel color given in 11.3.6 is:
+ * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
+ * with B() being the blend function.
+ * Note that OVER is a special case of this operation, using B(Cb, Cs) = Cs
+ *
+ * These blend modes should match the SVG filter draft specification, as
+ * it has been designed to mirror ISO 32000. Note that at the current point
+ * no released draft exists that shows this, as the formulas have not been
+ * updated yet after the release of ISO 32000.
+ *
+ * The default implementation here uses the PDF_SEPARABLE_BLEND_MODE and
+ * PDF_NON_SEPARABLE_BLEND_MODE macros, which take the blend function as an
+ * argument. Note that this implementation operates on premultiplied colors,
+ * while the PDF specification does not. Therefore the code uses the formula
+ * ar.Cra = (1 – as) . Dca + (1 – ad) . Sca + B(Dca, ad, Sca, as)

+ * PDF nonseperable blend modes.
+ *
+ * These are implemented using the following functions to operate in Hsl
+ * space, with Cmax, Cmid, Cmin referring to the max, mid and min value
+ * of the red, green and blue components.
+ *
+ * LUM (C) = 0.3 × Cred + 0.59 × Cgreen + 0.11 × Cblue
+ *
+ * clip_color (C):
+ *   l = LUM (C)
+ *   min = Cmin
+ *   max = Cmax
+ *   if n < 0.0
+ *     C = l + (((C – l) × l) ⁄     (l – min))
+ *   if x > 1.0
+ *     C = l + (((C – l) × (1 – l)) (max – l))
+ *   return C
+ *
+ * set_lum (C, l):
+ *   d = l – LUM (C)
+ *   C += d
+ *   return clip_color (C)
+ *
+ * SAT (C) = CH_MAX (C) - CH_MIN (C)
+ *
+ * set_sat (C, s):
+ *  if Cmax > Cmin
+ *    Cmid = ( ( ( Cmid – Cmin ) × s ) ⁄ ( Cmax – Cmin ) )
+ *    Cmax = s
+ *  else
+ *    Cmid = Cmax = 0.0
+ *  Cmin = 0.0
+ *  return C
+ */
+
+/* For premultiplied colors, we need to know what happens when C is
+ * multiplied by a real number. LUM and SAT are linear:
+ *
+ *    LUM (r × C) = r × LUM (C)		SAT (r × C) = r × SAT (C)
+ *
+ * If we extend clip_color with an extra argument a and change
+ *
+ *        if x >= 1.0
+ *
+ * into
+ *
+ *        if x >= a
+ *
+ * then clip_color is also linear:
+ *
+ *     r * clip_color (C, a) = clip_color (r_c, ra);
+ *
+ * for positive r.
+ *
+ * Similarly, we can extend set_lum with an extra argument that is just passed
+ * on to clip_color:
+ *
+ *     r × set_lum ( C, l, a)
+ *
+ *   = r × clip_color ( C + l - LUM (C), a)
+ *
+ *   = clip_color ( r * C + r × l - LUM (r × C), r * a)
+ *
+ *   = set_lum ( r * C, r * l, r * a)
+ *
+ * Finally, set_sat:
+ *
+ *     r * set_sat (C, s) = set_sat (x * C, r * s)
+ *
+ * The above holds for all non-zero x because they x'es in the fraction for
+ * C_mid cancel out. Specifically, it holds for x = r:
+ *
+ *     r * set_sat (C, s) = set_sat (r_c, rs)
+ *
+ *
+ *
+ *
+ * So, for the non-separable PDF blend modes, we have (using s, d for
+ * non-premultiplied colors, and S, D for premultiplied:
+ *
+ *   Color:
+ *
+ *     a_s * a_d * B(s, d)
+ *   = a_s * a_d * set_lum (S/a_s, LUM (D/a_d), 1)
+ *   = set_lum (S * a_d, a_s * LUM (D), a_s * a_d)
+ *
+ *
+ *   Luminosity:
+ *
+ *     a_s * a_d * B(s, d)
+ *   = a_s * a_d * set_lum (D/a_d, LUM(S/a_s), 1)
+ *   = set_lum (a_s * D, a_d * LUM(S), a_s * a_d)
+ *
+ *
+ *   Saturation:
+ *
+ *     a_s * a_d * B(s, d)
+ *   = a_s * a_d * set_lum (set_sat (D/a_d, SAT (S/a_s)), LUM (D/a_d), 1)
+ *   = set_lum (a_s * a_d * set_sat (D/a_d, SAT (S/a_s)),
+ *                                        a_s * LUM (D), a_s * a_d)
+ *   = set_lum (set_sat (a_s * D, a_d * SAT (S), a_s * LUM (D), a_s * a_d))
+ *
+ *   Hue:
+ *
+ *     a_s * a_d * B(s, d)
+ *   = a_s * a_d * set_lum (set_sat (S/a_s, SAT (D/a_d)), LUM (D/a_d), 1)

+ * specification, which at this point in time is available from
+ * http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf
+ * The relevant chapters are 11.3.5 and 11.3.6.
+ * The formula for computing the final pixel color given in 11.3.6 is:
+ * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
+ * with B() being the blend function.
+ * Note that OVER is a special case of this operation, using B(Cb, Cs) = Cs
+ *
+ * These blend modes should match the SVG filter draft specification, as
+ * it has been designed to mirror ISO 32000. Note that at the current point
+ * no released draft exists that shows this, as the formulas have not been
+ * updated yet after the release of ISO 32000.
+ *
+ * The default implementation here uses the PDF_SEPARABLE_BLEND_MODE and
+ * PDF_NON_SEPARABLE_BLEND_MODE macros, which take the blend function as an
+ * argument. Note that this implementation operates on premultiplied colors,
+ * while the PDF specification does not. Therefore the code uses the formula

+ * PDF blend modes:
+ * The following blend modes have been taken from the PDF ISO 32000
+ * specification, which at this point in time is available from
+ * http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf
+ * The relevant chapters are 11.3.5 and 11.3.6.
+ * The formula for computing the final pixel color given in 11.3.6 is:
+ * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
+ * with B() being the blend function.
+ * Note that OVER is a special case of this operation, using B(Cb, Cs) = Cs
+ *
+ * These blend modes should match the SVG filter draft specification, as
+ * it has been designed to mirror ISO 32000. Note that at the current point
+ * no released draft exists that shows this, as the formulas have not been
+ * updated yet after the release of ISO 32000.
+ *
+ * The default implementation here uses the PDF_SEPARABLE_BLEND_MODE and
+ * PDF_NON_SEPARABLE_BLEND_MODE macros, which take the blend function as an
+ * argument. Note that this implementation operates on premultiplied colors,
+ * while the PDF specification does not. Therefore the code uses the formula
+ * Cra = (1 – as) . Dca + (1 – ad) . Sca + B(Dca, ad, Sca, as)

+ * PDF blend modes:

+ * specification, which at this point in time is available from
+ * http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf
+ * The relevant chapters are 11.3.5 and 11.3.6.
+ * The formula for computing the final pixel color given in 11.3.6 is:
+ * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
+ * with B() being the blend function.
+ * Note that OVER is a special case of this operation, using B(Cb, Cs) = Cs
+ *
+ * These blend modes should match the SVG filter draft specification, as
+ * it has been designed to mirror ISO 32000. Note that at the current point
+ * no released draft exists that shows this, as the formulas have not been
+ * updated yet after the release of ISO 32000.
+ *
+ * The default implementation here uses the PDF_SEPARABLE_BLEND_MODE and
+ * PDF_NON_SEPARABLE_BLEND_MODE macros, which take the blend function as an
+ * argument. Note that this implementation operates on premultiplied colors,
+ * while the PDF specification does not. Therefore the code uses the formula
+ * Cra = (1 – as) . Dca + (1 – ad) . Sca + B(Dca, ad, Sca, as)

+ *  weight_bottom       - weight of the bottom row for interpolation
+ *  vx                  - initial position for fetching the first pair of
+ *                        pixels from the source buffer
+ *  unit_x              - position increment needed to move to the next pair
+ *                        of pixels
+ *  max_vx              - image size as a fixed point value, can be used for

+ *                        zone for NONE repeat
+ *
+ * Note: normally the sum of 'weight_top' and 'weight_bottom' is equal to 256,

+ * window as the source. It would create a pixman image pointing
+ * to some bogus position in memory, but then set a clip region
+ * to the position where the actual bits were.
+ *
+ * Due to a bug in old versions of pixman, where it would not clip
+ * against the image bounds when a clip region was set, this would
+ * actually work. So when the pixman bug was fixed, a workaround was
+ * added to allow certain out-of-bound accesses. This function disabled
+ * those workarounds.

+ * Since 0.21.2, pixman doesn't do these workarounds anymore, so now

+     * to any of the circles, it is transparent black, i.e. RGBA (0, 0, 0, 0).
+     * Further limitations on the range of values for t are imposed when
+     * the gradient is not repeated, namely t must belong to [0,1].
+     *
+     * The graphical result is the same as drawing the valid (radius > 0)
+     * circles with increasing t in [-inf, +inf] (or in [0,1] if the gradient
+     * is not repeated) using SOURCE operator composition.
+     *
+     * It looks like a cone pointing towards the viewer if the ending circle
+     * is smaller than the starting one, a cone pointing inside the page if
+     * the starting circle is the smaller one and like a cylinder if they
+     * have the same radius.
+     *
+     * What we actually do is, given the point whose color we are interested
+     * in, compute the t values for that point, solving for t in:
+     *
+     *     length((1-t)·c₁ + t·(c₂) - p) = (1-t)·r₁ + t·r₂
+     *

+     * If we impose (as stated earlier) that r₁ + t·dr >= 0, it becomes:
+     *
+     *     (t·cdx - pdx)² + (t·cdy - pdy)² = (r₁ + t·dr)²
+     *
+     * where we can actually expand the squares and solve for t:
+     *
+     *     t²cdx² - 2t·cdx·pdx + pdx² + t²cdy² - 2t·cdy·pdy + pdy² =
+     *       = r₁² + 2·r₁·t·dr + t²·dr²
+     *
+     *     (cdx² + cdy² - dr²)t² - 2(cdx·pdx + cdy·pdy + r₁·dr)t +
+     *         (pdx² + pdy² - r₁²) = 0

+     *     C = pdx² + pdy² - r₁²
+     *     At² - 2Bt + C = 0
+     *

+ * The functions in this file implement the Region abstraction used extensively
+ * throughout the X11 sample server. A Region is simply a set of disjoint
+ * (non-overlapping) rectangles, plus an "extent" rectangle which is the
+ * smallest single rectangle that contains all the non-overlapping rectangles.
+ *
+ * A Region is implemented as a "y-x-banded" array of rectangles.  This array
+ * imposes two degrees of order.  First, all rectangles are sorted by top side
+ * y coordinate first (y1), and then by left side x coordinate (x1).
+ *
+ * Furthermore, the rectangles are grouped into "bands".  Each rectangle in a
+ * band has the same top y coordinate (y1), and each has the same bottom y
+ * coordinate (y2).  Thus all rectangles in a band differ only in their left
+ * and right side (x1 and x2).  Bands are implicit in the array of rectangles:
+ * there is no separate list of band start pointers.
+ *
+ * The y-x band representation does not minimize rectangles.  In particular,
+ * if a rectangle vertically crosses a band (the rectangle has scanlines in
+ * the y1 to y2 area spanned by the band), then the rectangle may be broken
+ * down into two or more smaller rectangles stacked one atop the other.
+ *
+ *  -----------				    -----------
+ *  |         |				    |         |		    band 0
+ *  |         |  --------		    -----------  --------
+ *  |         |  |      |  in y-x banded    |         |  |      |   band 1
+ *  |         |  |      |  form is	    |         |  |      |
+ *  -----------  |      |		    -----------  --------
+ *               |      |				 |      |   band 2
+ *               --------				 --------
+ *
+ * An added constraint on the rectangles is that they must cover as much
+ * horizontal area as possible: no two rectangles within a band are allowed
+ * to touch.
+ *
+ * Whenever possible, bands will be merged together to cover a greater vertical
+ * distance (and thus reduce the number of rectangles). Two bands can be merged
+ * only if the bottom of one touches the top of the other and they have
+ * rectangles in the same places (of the same width, of course).
+ *
+ * Adam de Boor wrote most of the original region code.  Joel McCormack
+ * substantially modified or rewrote most of the core arithmetic routines, and
+ * added pixman_region_validate in order to support several speed improvements
+ * to pixman_region_validate_tree.  Bob Scheifler changed the representation
+ * to be more compact when empty or a single rectangle, and did a bunch of
+ * gratuitous reformatting. Carl Worth did further gratuitous reformatting
+ * while re-merging the server and client region code into libpixregion.
+ * Soren Sandmann did even more gratuitous reformatting.

+/* Executive Summary: This function is a no-op that only exists
+ * for historical reasons.
+ *
+ * There used to be a bug in the X server where it would rely on
+ * out-of-bounds accesses when it was asked to composite with a
+ * window as the source. It would create a pixman image pointing
+ * to some bogus position in memory, but then set a clip region
+ * to the position where the actual bits were.
+ *
+ * Due to a bug in old versions of pixman, where it would not clip
+ * against the image bounds when a clip region was set, this would
+ * actually work. So when the pixman bug was fixed, a workaround was
+ * added to allow certain out-of-bound accesses. This function disabled

+Roadmap
+
+- Move all the fetchers etc. into pixman-image to make pixman-compose.c
+  less intimidating.
+
+  DONE
+
+- Make combiners for unified alpha take a mask argument. That way
+  we won't need two separate paths for unified vs component in the
+  general compositing code.
+
+  DONE, except that the Altivec code needs to be updated. Luca is
+  looking into that.
+
+- Delete separate 'unified alpha' path
+ 
+  DONE
+
+- Split images into their own files
+
+  DONE
+
+- Split the gradient walker code out into its own file
+
+  DONE
+
+- Add scanline getters per image
+
+  DONE
+
+- Generic 64 bit fetcher 
+
+  DONE
+
+- Split fast path tables into their respective architecture dependent
+  files.
+
+See "Render Algorithm" below for rationale
+
+Images will eventually have these virtual functions:
+
+       get_scanline()
+       get_scanline_wide()
+       get_pixel()
+       get_pixel_wide()
+       get_untransformed_pixel()
+       get_untransformed_pixel_wide()
+       get_unfiltered_pixel()
+       get_unfiltered_pixel_wide()
+
+       store_scanline()
+       store_scanline_wide()
+
+1.
+
+Initially we will just have get_scanline() and get_scanline_wide();
+these will be based on the ones in pixman-compose. Hopefully this will
+reduce the complexity in pixman_composite_rect_general().
+
+Note that there is access considerations - the compose function is
+being compiled twice.
+
+
+2.
+
+Split image types into their own source files. Export noop virtual
+reinit() call.  Call this whenever a property of the image changes.
+
+
+3. 
+
+Split the get_scanline() call into smaller functions that are
+initialized by the reinit() call.
+
+The Render Algorithm:
+	(first repeat, then filter, then transform, then clip)
+
+Starting from a destination pixel (x, y), do
+
+	1 x = x - xDst + xSrc
+	  y = y - yDst + ySrc
+
+	2 reject pixel that is outside the clip
+
+	This treats clipping as something that happens after
+	transformation, which I think is correct for client clips. For
+	hierarchy clips it is wrong, but who really cares? Without
+	GraphicsExposes hierarchy clips are basically irrelevant. Yes,
+	you could imagine cases where the pixels of a subwindow of a
+	redirected, transformed window should be treated as
+	transparent. I don't really care
+
+	Basically, I think the render spec should say that pixels that
+	are unavailable due to the hierarcy have undefined content,
+	and that GraphicsExposes are not generated. Ie., basically
+	that using non-redirected windows as sources is fail. This is
+	at least consistent with the current implementation and we can
+	update the spec later if someone makes it work.
+
+	The implication for render is that it should stop passing the
+	hierarchy clip to pixman. In pixman, if a souce image has a
+	clip it should be used in computing the composite region and
+	nowhere else, regardless of what "has_client_clip" says. The
+	default should be for there to not be any clip.
+
+	I would really like to get rid of the client clip as well for
+	source images, but unfortunately there is at least one
+	application in the wild that uses them.
+
+	3 Transform pixel: (x, y) = T(x, y)
+
+	4 Call p = GetUntransformedPixel (x, y)
+
+	5 If the image has an alpha map, then
+
+		Call GetUntransformedPixel (x, y) on the alpha map
+		
+		add resulting alpha channel to p
+
+	   return p
+
+	Where GetUnTransformedPixel is:
+
+	6 switch (filter)
+	  {
+	  case NEAREST:
+		return GetUnfilteredPixel (x, y);
+		break;
+
+	  case BILINEAR:
+		return GetUnfilteredPixel (...) // 4 times 
+		break;
+
+	  case CONVOLUTION:
+		return GetUnfilteredPixel (...) // as many times as necessary.
+		break;
+	  }
+
+	Where GetUnfilteredPixel (x, y) is
+
+	7 switch (repeat)
+	   {
+	   case REPEAT_NORMAL:
+	   case REPEAT_PAD:
+	   case REPEAT_REFLECT:
+		// adjust x, y as appropriate
+		break;
+
+	   case REPEAT_NONE:
+	        if (x, y) is outside image bounds
+		     return 0;
+		break;
+	   }
+
+	   return GetRawPixel(x, y)
+
+	Where GetRawPixel (x, y) is
+
+	8 Compute the pixel in question, depending on image type.
+
+For gradients, repeat has a totally different meaning, so
+UnfilteredPixel() and RawPixel() must be the same function so that
+gradients can do their own repeat algorithm.
+
+So, the GetRawPixel
+
+	for bits must deal with repeats
+	for gradients must deal with repeats (differently)
+	for solids, should ignore repeats.
+
+	for polygons, when we add them, either ignore repeats or do
+	something similar to bits (in which case, we may want an extra
+	layer of indirection to modify the coordinates).
+
+It is then possible to build things like "get scanline" or "get tile" on
+top of this. In the simplest case, just repeatedly calling GetPixel()
+would work, but specialized get_scanline()s or get_tile()s could be
+plugged in for common cases. 
+
+By not plugging anything in for images with access functions, we only
+have to compile the pixel functions twice, not the scanline functions.
+
+And we can get rid of fetchers for the bizarre formats that no one
+uses. Such as b2g3r3 etc. r1g2b1? Seriously? It is also worth
+considering a generic format based pixel fetcher for these edge cases.
+
+Since the actual routines depend on the image attributes, the images
+must be notified when those change and update their function pointers
+appropriately. So there should probably be a virtual function called
+(* reinit) or something like that.
+
+There will also be wide fetchers for both pixels and lines. The line
+fetcher will just call the wide pixel fetcher. The wide pixel fetcher
+will just call expand, except for 10 bit formats.
+
+Rendering pipeline:
+
+Drawable:
+	0. if (picture has alpha map)
+		0.1. Position alpha map according to the alpha_x/alpha_y
+	        0.2. Where the two drawables intersect, the alpha channel
+		     Replace the alpha channel of source with the one
+		     from the alpha map. Replacement only takes place
+		     in the intersection of the two drawables' geometries.
+	1. Repeat the drawable according to the repeat attribute
+	2. Reconstruct a continuous image according to the filter
+	3. Transform according to the transform attribute
+	4. Position image such that src_x, src_y is over dst_x, dst_y
+	5. Sample once per destination pixel 
+	6. Clip. If a pixel is not within the source clip, then no
+	   compositing takes place at that pixel. (Ie., it's *not*
+	   treated as 0).
+
+	Sampling a drawable: 
+
+	- If the channel does not have an alpha channel, the pixels in it
+	  are treated as opaque.
+
+	Note on reconstruction:
+
+	- The top left pixel has coordinates (0.5, 0.5) and pixels are
+	  spaced 1 apart.
+
+Gradient:
+	1. Unless gradient type is conical, repeat the underlying (0, 1)
+		gradient according to the repeat attribute
+	2. Integrate the gradient across the plane according to type.
+	3. Transform according to transform attribute
+	4. Position gradient 
+	5. Sample once per destination pixel.
+ 	6. Clip
+
+Solid Fill:
+	1. Repeat has no effect
+	2. Image is already continuous and defined for the entire plane
+	3. Transform has no effect
+	4. Positioning has no effect
+	5. Sample once per destination pixel.
+	6. Clip
+
+Polygon:
+	1. Repeat has no effect
+	2. Image is already continuous and defined on the whole plane
+	3. Transform according to transform attribute
+	4. Position image
+	5. Supersample 15x17 per destination pixel.
+	6. Clip
+
+Possibly interesting additions:
+	- More general transformations, such as warping, or general
+	  shading.
+
+	- Shader image where a function is called to generate the
+          pixel (ie., uploading assembly code).
+
+	- Resampling kernels
+
+	  In principle the polygon image uses a 15x17 box filter for
+	  resampling. If we allow general resampling filters, then we
+	  get all the various antialiasing types for free. 
+
+	  Bilinear downsampling looks terrible and could be much 
+	  improved by a resampling filter. NEAREST reconstruction
+	  combined with a box resampling filter is what GdkPixbuf
+	  does, I believe.
+
+	  Useful for high frequency gradients as well.
+
+	  (Note that the difference between a reconstruction and a
+	  resampling filter is mainly where in the pipeline they
+	  occur. High quality resampling should use a correctly
+	  oriented kernel so it should happen after transformation.
+
+	  An implementation can transform the resampling kernel and
+	  convolve it with the reconstruction if it so desires, but it
+	  will need to deal with the fact that the resampling kernel
+	  will not necessarily be pixel aligned.
+
+	  "Output kernels"
+
+	  One could imagine doing the resampling after compositing,
+	  ie., for each destination pixel sample each source image 16
+	  times, then composite those subpixels individually, then
+	  finally apply a kernel.
+
+	  However, this is effectively the same as full screen
+	  antialiasing, which is a simpler way to think about it. So
+	  resampling kernels may make sense for individual images, but
+	  not as a post-compositing step.
+	  
+	  Fullscreen AA is inefficient without chained compositing
+	  though. Consider an (image scaled up to oversample size IN
+	  some polygon) scaled down to screen size. With the current
+	  implementation, there will be a huge temporary. With chained
+	  compositing, the whole thing ends up being equivalent to the
+	  output kernel from above.
+
+	- Color space conversion
+
+	  The complete model here is that each surface has a color
+	  space associated with it and that the compositing operation
+	  also has one associated with it. Note also that gradients
+	  should have associcated colorspaces.
+
+	- Dithering
+
+	  If people dither something that is already dithered, it will
+	  look terrible, but don't do that, then. (Dithering happens
+	  after resampling if at all - what is the relationship
+	  with color spaces? Presumably dithering should happen in linear
+	  intensity space).
+
+	- Floating point surfaces, 16, 32 and possibly 64 bit per
+	  channel.
+
+	Maybe crack:
+
+	- Glyph polygons
+
+	  If glyphs could be given as polygons, they could be
+	  positioned and rasterized more accurately. The glyph
+	  structure would need subpixel positioning though.
+
+	- Luminance vs. coverage for the alpha channel
+
+	  Whether the alpha channel should be interpreted as luminance
+          modulation or as coverage (intensity modulation). This is a
+          bit of a departure from the rendering model though. It could
+	  also be considered whether it should be possible to have 
+	  both channels in the same drawable.
+
+	- Alternative for component alpha
+
+	  - Set component-alpha on the output image.
+
+	    - This means each of the components are sampled
+	      independently and composited in the corresponding
+	      channel only.
+
+	  - Have 3 x oversampled mask
+
+	  - Scale it down by 3 horizontally, with [ 1/3, 1/3, 1/3 ]
+            resampling filter. 
+
+	    Is this equivalent to just using a component alpha mask?
+
+	Incompatible changes:
+
+	- Gradients could be specified with premultiplied colors. (You
+	  can use a mask to get things like gradients from solid red to
+	  transparent red.
+
+Refactoring pixman
+
+The pixman code is not particularly nice to put it mildly. Among the
+issues are
+
+- inconsistent naming style (fb vs Fb, camelCase vs
+  underscore_naming). Sometimes there is even inconsistency *within*
+  one name.
+
+      fetchProc32 ACCESS(pixman_fetchProcForPicture32)
+
+  may be one of the uglies names ever created.
+
+  coding style: 
+  	 use the one from cairo except that pixman uses this brace style:
+	 
+		while (blah)
+		{
+		}
+
+	Format do while like this:
+
+	       do 
+	       {
+
+	       } 
+	       while (...);
+
+- PIXMAN_COMPOSITE_RECT_GENERAL() is horribly complex
+
+- switch case logic in pixman-access.c
+
+  Instead it would be better to just store function pointers in the
+  image objects themselves,
+
+  	get_pixel()
+	get_scanline()
+
+- Much of the scanline fetching code is for formats that no one 
+  ever uses. a2r2g2b2 anyone?
+
+  It would probably be worthwhile having a generic fetcher for any
+  pixman format whatsoever.
+
+- Code related to particular image types should be split into individual
+  files.
+
+	pixman-bits-image.c
+	pixman-linear-gradient-image.c
+	pixman-radial-gradient-image.c
+	pixman-solid-image.c
+
+- Fast path code should be split into files based on architecture:
+
+       pixman-mmx-fastpath.c
+       pixman-sse2-fastpath.c
+       pixman-c-fastpath.c
+
+       etc.
+
+  Each of these files should then export a fastpath table, which would
+  be declared in pixman-private.h. This should allow us to get rid
+  of the pixman-mmx.h files.
+
+  The fast path table should describe each fast path. Ie there should
+  be bitfields indicating what things the fast path can handle, rather than
+  like now where it is only allowed to take one format per src/mask/dest. Ie., 
+
+  { 
+    FAST_a8r8g8b8 | FAST_x8r8g8b8,
+    FAST_null,
+    FAST_x8r8g8b8,
+    FAST_repeat_normal | FAST_repeat_none,
+    the_fast_path
+  }
+
+There should then be *one* file that implements pixman_image_composite(). 
+This should do this:
+
+     optimize_operator();
+
+     convert 1x1 repeat to solid (actually this should be done at
+     image creation time).
+     
+     is there a useful fastpath?
+
+There should be a file called pixman-cpu.c that contains all the
+architecture specific stuff to detect what CPU features we have.
+
+Issues that must be kept in mind:
+
+       - we need accessor code to be preserved
+
+       - maybe there should be a "store_scanline" too?
+
+         Is this sufficient?
+
+	 We should preserve the optimization where the
+	 compositing happens directly in the destination
+	 whenever possible.
+
+	- It should be possible to create GPU samplers from the
+	  images.
+
+The "horizontal" classification should be a bit in the image, the
+"vertical" classification should just happen inside the gradient
+file. Note though that
+
+      (a) these will change if the tranformation/repeat changes.
+
+      (b) at the moment the optimization for linear gradients
+          takes the source rectangle into account. Presumably
+	  this is to also optimize the case where the gradient
+	  is close enough to horizontal?
+
+Who is responsible for repeats? In principle it should be the scanline
+fetch. Right now NORMAL repeats are handled by walk_composite_region()
+while other repeats are handled by the scanline code.
+
+
+(Random note on filtering: do you filter before or after
+transformation?  Hardware is going to filter after transformation;
+this is also what pixman does currently). It's not completely clear
+what filtering *after* transformation means. One thing that might look
+good would be to do *supersampling*, ie., compute multiple subpixels
+per destination pixel, then average them together.
