+ * Implementation of a triple box blur approximation of a Gaussian blur.
+ *
+ * A Gaussian blur is good for blurring because, when done independently
+ * in the horizontal and vertical directions, it matches the result that
+ * would be obtained using a different (rotated) set of axes.  A triple
+ * box blur is a very close approximation of a Gaussian.
+ *
+ * This is a "service" class; the constructors set up all the information
+ * based on the values and compute the minimum size for an 8-bit alpha
+ * channel context.
+ * The callers are responsible for creating and managing the backing surface
+ * and passing the pointer to the data to the Blur() method.  This class does
+ * not retain the pointer to the data outside of the Blur() call.
+ *
+ * A spread N makes each output pixel the maximum value of all source
+ * pixels within a square of side length 2N+1 centered on the output pixel.

+ * We have to do a lot of work to draw glyphs with CG because
+ * CG assumes that the origin of rects are in the bottom left
+ * while every other DrawTarget assumes the top left is the origin.
+ * This means we have to transform the CGContext to have rects
+ * actually be applied in top left fashion. We do this by:
+ *
+ * 1) Translating the context up by the height of the canvas
+ * 2) Flipping the context by the Y axis so it's upside down.
+ *
+ * These two transforms put the origin in the top left.
+ * Transforms are better understood thinking about them from right to left order (mathematically).
+ *
+ * Consider a point we want to draw at (0, 10) in normal cartesian planes with
+ * a box of (100, 100). in CG terms, this would be at (0, 10).
+ * Positive Y values point up.
+ * In our DrawTarget terms, positive Y values point down, so (0, 10) would be
+ * at (0, 90) in cartesian plane terms. That means our point at (0, 10) in DrawTarget
+ * terms should end up at (0, 90). How does this work with the current transforms?
+ *
+ * Going right to left with the transforms, a CGPoint of (0, 10) has cartesian coordinates
+ * of (0, 10). The first flip of the Y axis puts the point now at (0, -10);
+ * Next, we translate the context up by the size of the canvas (Positive Y values go up in CG
+ * coordinates but down in our draw target coordinates). Since our canvas size is (100, 100),
+ * the resulting coordinate becomes (0, 90), which is what we expect from our DrawTarget code.
+ * These two transforms put the CG context equal to what every other DrawTarget expects.
+ *
+ * Next, we need two more transforms for actual text. IF we left the transforms as is,
+ * the text would be drawn upside down, so we need another flip of the Y axis
+ * to draw the text right side up. However, with only the flip, the text would be drawn
+ * in the wrong place. Thus we also have to invert the Y position of the glyphs to get them
+ * in the right place.
+ *
+ * Thus we have the following transforms:
+ * 1) Translation of the context up
+ * 2) Flipping the context around the Y axis
+ * 3) Flipping the context around the Y axis
+ * 4) Inverting the Y position of each glyph
+ *
+ * We cannot cancel out (2) and (3) as we have to apply the clips and transforms
+ * of DrawTargetSkia between (2) and (3).
+ *
+ * Consider the example letter P, drawn at (0, 20) in CG coordinates in a (100, 100) rect.
+ * Again, going right to left of the transforms. We'd get:
+ *
+ * 1) The letter P drawn at (0, -20) due to the inversion of the Y axis
+ * 2) The letter P upside down (b) at (0, 20) due to the second flip
+ * 3) The letter P right side up at (0, -20) due to the first flip
+ * 4) The letter P right side up at (0, 80) due to the translation
+ *
+ * tl;dr - CGRects assume origin is bottom left, DrawTarget rects assume top left.

+  // In order to determine whether the input needs to be unpremultiplied as

+  // and giving Moz2D users different results based on something that cannot be
+  // influenced through Moz2D APIs seems like a bad idea.
+  // We solve this by applying a premultiply effect to the input before feeding
+  // it into the transfer effect. The premultiply effect always premultiplies
+  // regardless of any alpha mode metadata on inputs, and it always marks its
+  // output as premultiplied so that the transfer effect will unpremultiply
+  // consistently. Feeding always-premultiplied input into the transfer effect
+  // also avoids another problem that would appear when individual color
+  // channels disable the transfer: In that case, the disabled channels would
+  // pass through unchanged in their unpremultiplied form and the other
+  // channels would be premultiplied, giving a mixed result.
+  // But since we now ensure that the input is premultiplied, disabled channels
+  // will pass premultiplied values through to the result, which is consistent
+  // with the enabled channels.

+/* The functions below use the following system for averaging 4 pixels:
+ *
+ * The first observation is that a half-adder is implemented as follows:
+ * R = S + 2C or in the case of a and b (a ^ b) + ((a & b) << 1);
+ *
+ * This can be trivially extended to three pixels by observaring that when
+ * doing (a ^ b ^ c) as the sum, the carry is simply the bitwise-or of the
+ * carries of the individual numbers, since the sum of 3 bits can only ever
+ * have a carry of one.
+ *
+ * We then observe that the average is then ((carry << 1) + sum) >> 1, or,
+ * assuming eliminating overflows and underflows, carry + (sum >> 1).
+ *
+ * We now average our existing sum with the fourth number, so we get:
+ * sum2 = (sum + d) >> 1 or (sum >> 1) + (d >> 1).
+ *
+ * We now observe that our sum has been moved into place relative to the
+ * carry, so we can now average with the carry to get the final 4 input
+ * average: avg = (sum2 + carry) >> 1;
+ *
+ * Or to reverse the proof:
+ * avg = ((sum >> 1) + carry + d >> 1) >> 1
+ * avg = ((a + b + c) >> 1 + d >> 1) >> 1
+ * avg = ((a + b + c + d) >> 2)
+ *
+ * An additional fact used in the SSE versions is the concept that we can
+ * trivially convert a rounded average to a truncated average:
+ *
+ * We have:
+ * f(a, b) = (a + b + 1) >> 1
+ *
+ * And want:
+ * g(a, b) = (a + b) >> 1
+ *
+ * Observe:
+ * ~f(~a, ~b) == ~((~a + ~b + 1) >> 1)
+ *            == ~((-a - 1 + -b - 1 + 1) >> 1)
+ *            == ~((-a - 1 + -b) >> 1)
+ *            == ~((-(a + b) - 1) >> 1)
+ *            == ~((~(a + b)) >> 1)
+ *            == (a + b) >> 1

+/* Find the inflection points of a bezier curve. Will return false if the
+ * curve is degenerate in such a way that it is best approximated by a straight
+ * line.
+ *
+ * The below algorithm was written by Jeff Muizelaar <jmuizelaar@mozilla.com>, explanation follows:
+ *
+ * The lower inflection point is returned in aT1, the higher one in aT2. In the
+ * case of a single inflection point this will be in aT1.
+ *
+ * The method is inspired by the algorithm in "analysis of in?ection points for planar cubic bezier curve"
+ *
+ * Here are some differences between this algorithm and versions discussed elsewhere in the literature:
+ *
+ * zhang et. al compute a0, d0 and e0 incrementally using the follow formula:
+ *
+ * Point a0 = CP2 - CP1
+ * Point a1 = CP3 - CP2
+ * Point a2 = CP4 - CP1
+ *
+ * Point d0 = a1 - a0
+ * Point d1 = a2 - a1
+ 
+ * Point e0 = d1 - d0
+ *
+ * this avoids any multiplications and may or may not be faster than the approach take below.
+ *
+ * "fast, precise flattening of cubic bezier path and ofset curves" by hain et. al
+ * Point a = CP1 + 3 * CP2 - 3 * CP3 + CP4
+ * Point b = 3 * CP1 - 6 * CP2 + 3 * CP3
+ * Point c = -3 * CP1 + 3 * CP2
+ * Point d = CP1
+ * the a, b, c, d can be expressed in terms of a0, d0 and e0 defined above as:
+ * c = 3 * a0
+ * b = 3 * d0
+ * a = e0
+ *
+ *
+ * a = 3a = a.y * b.x - a.x * b.y
+ * b = 3b = a.y * c.x - a.x * c.y
+ * c = 9c = b.y * c.x - b.x * c.y
+ *
+ * The additional multiples of 3 cancel each other out as show below:
+ *
+ * x = (-b + sqrt(b * b - 4 * a * c)) / (2 * a)
+ * x = (-3 * b + sqrt(3 * b * 3 * b - 4 * a * 3 * 9 * c / 3)) / (2 * 3 * a)
+ * x = 3 * (-b + sqrt(b * b - 4 * a * c)) / (2 * 3 * a)
+ * x = (-b + sqrt(b * b - 4 * a * c)) / (2 * a)
+ *
+ * I haven't looked into whether the formulation of the quadratic formula in
+ * hain has any numerical advantages over the one used below.

+  //      polynomials." Computer-Aided Geometric Design 8(1991) 227--238.

+  //      quadratic, or cubic Bezier curves."
+  //      http://www.spaceroots.org/documents/ellipse/elliptical-arc.pdf
+  //
+  // We follow the approach in section 2 of Goldapp (least-error,
+  // Hermite-type approximation) and make both ratios equal to
+  //
+  //          2   2 + n - sqrt(2n + 28)
+  //  alpha = - * ---------------------
+  //          3           n - 4

+  //
+  // This is the result of Goldapp's equation (10b) when the angle
+  // swept out by the arc is pi/2, and the parameter "a-bar" is the
+  // expression given immediately below equation (21).
+  //
+  // Using this value, the maximum radial error for a circle, as a

+// source become p pixels in the destination) will have a period of p.
+// A nice consequence is a period of 1 when downscaling by an integral
