Issue #146 - Part 2: Remove custom table painting component.
Since we're now putting table borders and backgrounds properly in the display lists, we no longer need this custom component to do this work for us.

-/* ~*~ Table Background Painting ~*~
-
- Mozilla's Table Background painting follows CSS2.1:17.5.1
- That section does not, however, describe the effect of
- borders on background image positioning. What we do is:
-
- - in separate borders, the borders are passed in so that
- their width figures in image positioning, even for rows/cols, which
- don't have visible borders. This is done to allow authors
- to position row backgrounds by, for example, aligning the
- top left corner with the top left padding corner of the
- top left table cell in the row in cases where all cells
- have consistent border widths. If we didn't honor these
- invisible borders, there would be no way to align
- backgrounds with the padding edges, and designs would be
- lost underneath the border.
-
- - in collapsing borders, because the borders collapse, we
- use the -continuous border- width to synthesize a border
- style and pass that in instead of using the element's
- assigned style directly.
-
- The continuous border on a given edge of an element is
- the collapse of all borders guaranteed to be continuous
- along that edge. Cell borders are ignored (because, for
- example, setting a thick border on the leftmost cell
- should not shift the row background over; this way a
- striped background set on <tr> will line up across rows
- even if the cells are assigned arbitrary border widths.
-
- For example, the continuous border on the top edge of a
- row group is the collapse of any row group, row, and
- table borders involved. (The first row group's top would
- be [table-top + row group top + first row top]. It's bottom
- would be [row group bottom + last row bottom + next row
- top + next row group top].)
- The top edge of a column group likewise includes the
- table top, row group top, and first row top borders. However,
- it *also* includes its own top border, since that is guaranteed
- to be continuous. It does not include column borders because
- those are not guaranteed to be continuous: there may be two
- columns with different borders in a single column group.
-
- An alternative would be to define the continuous border as
- [table? + row group + row] for horizontal
- [table? + col group + col] for vertical
- This makes it easier to line up backgrounds across elements
- despite varying border widths, but it does not give much
- flexibility in aligning /to/ those border widths.
-*/
-
-
-/* ~*~ TableBackgroundPainter ~*~
-
- The TableBackgroundPainter is created and destroyed in one painting call.
- Its principal function is PaintTable, which paints all table element
- backgrounds. The initial code in that method sets up an array of column
- data that caches the background styles and the border sizes for the
- columns and colgroups in TableBackgroundData structs in mCols. Data for
- BC borders are calculated and stashed in a synthesized border style struct
- in the data struct since collapsed borders aren't the same width as style-
- assigned borders. The data struct optimizes by only doing this if there's
- an image background; otherwise we don't care. //XXX should also check background-origin
- The class then loops through the row groups, rows, and cells. At the cell
- level, it paints the backgrounds, one over the other, inside the cell rect.
-
- The exception to this pattern is when a table element creates a (pseudo)
- stacking context. Elements with stacking contexts (e.g., 'opacity' applied)
- are <dfn>passed through</dfn>, which means their data (and their
- descendants' data) are not cached. The full loop is still executed, however,
- so that underlying layers can get painted at the cell level.
-
- The TableBackgroundPainter is then destroyed.
-
- Elements with stacking contexts set up their own painter to finish the
- painting process, since they were skipped. They call the appropriate
- sub-part of the loop (e.g. PaintRow) which will paint the frame and
- descendants.

- // Each table part layer has its position stored in the coordinate space of
- // the layer below (which is to say, its geometric parent), and the stored
- // position is the post-relative-positioning one. The position of each
- // background layer rect is thus determined by peeling off successive table
- // part layers, removing the contribution of each layer's positioning one by
- // one. Every rect we generate will be the same size, the size of the cell
