[AGG] OpenType font rendering

[Pierre A. <pie...@op...>]

While trying to implement painting of OpenType glyphs with
AGG, I have come across the first serious problem: not all
fonts have 'loca' and a 'glyf' tables...

The "Warnock Pro" font family, for instance, is a PostScript
font manipulated as an OpenType font, but it does not contain
outline definitions as specified for regular TrueType fonts.

I would have to handle the 'Type2' description, not only the
plain 'glyf' tables. This looks like it is more complicated
than expected. Using FreeType had saved me from the real low-
level implementation details.

Anyhow, I'll continue my work on the AGG glyph rendering,
without using any Windows system call (but GetFontData).
