Subject: BUG: handling italicized text

When a text run is italicized the overhanging part of the last
character of that run gets chopped off. In the past this only
happened on screen, but since we now support background
colours different than white, it now happens also while printing; this
makes it a very serious bug -- the printout looks really crappy.
The flaw is in assuming in fp_TextRun::_draw that each run and
any of its parts is contained in a rectangular region, which is not
true for italicized text. In order to fix this bug, we will have to
replace the _fillRect calls with _fillRegion call -- this will require new
pure virtual fillRegion in GR_Graphics class, plus some additional
changes to the xp font handling, so that the text run can determine
the overhang of text in italics.
I will try to implement the xp stuff and the win32 and gtk versions of
the pure virtuals over the weekend, and this is an advanced warning
that the changes will break all other platforms.
