I'm trying to figure out how justification affects nsLineBoxes (for bug 309761).
It looks like it updates the mData->mCombinedArea but not the mBounds at the
moment. Should it just be updating the mBounds? Or should painting text
decorations use mData->mCombinedArea? Based on the comments around the latter,
it sounds like it might include rel pos inlines, in which case using it for
text-decoration would be wrong.
Anyone know how this stuff works?
