FONTOBJ_cGetAllGlyphHandles allows the device driver to find every glyph handle of a GDI font. A driver uses this service to download an entire font.
The return value is the number of glyph handles supported by the font.
The driver must provide a buffer large enough to contain the output. GDI copies all glyph handles belonging to the associated font to this buffer.
The number of glyphs in the font can be determined by calling FONTOBJ_vGetInfo, or by calling FONTOBJ_cGetAllGlyphHandles with the phg parameter set to null.
