aFilter is useful for determining if a frame should output itself during
a List(). In any event, the children of the frame are always processed.
added nsIListFilter, an interface for any object that wants to act like a filter for frame dumps
added static NS_LAYOUT nsIListFilter * GetFilter(nsString *aFilterName);
currently, only TableListFilter implements nsIListFilter.
in response to List(...TableListFilter), the frame model is dumped in a way that is useful
for table layout regression testing. Currently this is controlled by command line switches on the viewer app.
this work exposed a few bugs and slow spots, which have been fixed
for the aol page, I added some additional backwards compatibility code
to proportionately distribute width when a fixed-width cell has colspans
1. cellmap couldn't properly delete CellData because definition was unavailable
2. optimized table cells made taller wouldn't shrink when they should because we were not
remembering the previous desired height of the cell.
3. rows were placing cells on the left edge, and not adding in the left margin.
from the prior available width. Some real-world test cases sped up
1-2 orders of magnitude for resize reflow. Initial reflow is unchanged because
we still need to get pass1 metrics on all content.
fixed nsCSSBlockFrame.cpp to take margins into account when computing parent's available width
fixed distribution of excess space to table cells when table is bigger than the content it holds.
not quite finished yet, but better.
Made DidSetStyleContext virtual, since we need to override the behavior in subclasses
Moved attribute setting logic from nsTableCell to nsTableCellFrame
Table Borders are being drawn again : )
Table Padding is being displayed
