[GDI FONT DRIVER]
Commit my first version of the font driver.
current status:
- It loads OpenType / Type1 files (couldn't test others)
- It creates all neccessary structures for later management
- It creates the glyphset (unicode->glyph handle translation)
- it creates an IFIMETRICS structure, based on freetype info and TTF/OTF OS/2 table data,
mostly complete
