Underline and strikethrough support

[Warren_Baird@cimmetry.com]

This is the first of a fairly long set of patches done by myself and my
development team - the patches are built against the jan 15th release.  I'm the
only person on the team with an external email address, so I've put my name on
all of the patches, and then the names of other team members that worked on the
patch.

ChangeLog:

     Add support for underline and strikethrough font in XRender.

Description:

     Use lfUnderline or lfStrikeOut logical font field in
     X11DRV_XRender_ExtTextOut to determine if we should draw a
     line using TSXDrawLine across or under the font that just got
     rendered.
