fixes for negative font width and multi-byte char support

[Warren_Baird at cimmetry.com]

ChangeLog:

     1. Added sanity check on width logical font field in CreateFontIndirect.
     2. Added multi-bytes character support for GetGlyphOutline.

Description:

     1. Passing a negative width in the logical font to the X11drv XRender
     library will somehow produce a crash.
