[Freetype] Retrieving font and glyph hints

[Wolfgang]

Hi all,

for a font analyzing tool, I am looking for a way to retrieve the font 
hints (e.g. PS Type 1 BlueValues) and the glyph hints (e.g. PS Type 1 
stems) using FreeType. Looking through the documentation and the 
sources, I could not find a way to get these values.

I can use FreeType's TrueType bytecode interpreter, because I will not 
render the characters to a raster device. This means that I can rely on 
the hinting coming from the drivers, but auto-hinted fonts should work 
as well.

Thank you for your help,

Wolfgang
