/* ~*~ Standards Mode Painting ~*~
Background painting in Standards mode 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 continous 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.
*/
/* ~*~ Quirks Table Background Painting ~*~
Quirks inherits all backgrounds below the table level into the
cells; we don't paint intermediate backgrounds.
*/
/* ~*~ 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. It uses
the mRowGroup and mRow TableBackgroundData structs to cache data for
the current frame in the loop. 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 has a view.
Elements with views 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 views 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.

/* ~*~ The Border Collapse Painting Issue ~*~
In border-collapse, the *table* paints the cells' borders,
so we need to make sure the backgrounds get painted first
(underneath) by doing a cell-background-only painting pass.
This happens in both Standards and Quirks mode PaintTable
calls.
The table must then do a no-cell-background pass that
continues as a normal background paint call in the cell
descendants.) This method doesn't handle views very well, but
then, nothing about BC table painting really does.
*/

A call to PaintTable will normally paint all of the table's
elements (except the cells in non-BC). Elements with views
however, will be skipped and must create their own painter
to call the appropriate paint function in their ::Paint
method (e.g. painter.PaintRow in nsTableRow::Paint)

/* ~*~ Standards Mode Painting ~*~
Background painting in Standards mode 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 continous 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.
*/
/* ~*~ Quirks Table Background Painting ~*~
Quirks inherits all backgrounds below the table level into the
cells; we don't paint intermediate backgrounds.
*/
/* ~*~ 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. It uses
the mRowGroup and mRow TableBackgroundData structs to cache data for
the current frame in the loop. 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 has a view.
Elements with views 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 views 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.

In border-collapse, the *table* paints the cells' borders,

(underneath) by doing a cell-background-only painting pass.
This happens in both Standards and Quirks mode PaintTable
calls.
The table must then do a no-cell-background pass that
continues as a normal background paint call in the cell
descendants.) This method doesn't handle views very well, but
then, nothing about BC table painting really does.

however, will be skipped and must create their own painter
to call the appropriate paint function in their ::Paint
method (e.g. painter.PaintRow in nsTableRow::Paint)
