If someone could implement glyph presence detection on Unix/xft I
would be grateful -- I have some nice code waiting to be turned on
that is conditioned by that. Also, once it is in place I will be able
to remove the dreaded GR_Graphics::remapGlyph() for ever.
As I said in an earlier posting, the glyph detection can be
implemented in two ways:
1. When measuring character widths for the cache if the glyph is
absent, set the width to GR_CW_ABSENT
2. Alternatively, implement GR_*Font::doesGlyphExist() to replace the
virtual implemented in the base class.
Choose whatever makes better sense (if you replace the
doesGlyphExist() function, the implementation needs to be fast).
