Re: [ft] freetype render mingliu.ttc

[Peter Hanzel]

Hello.

Yes I have checked it. It returns face->glyph->advance.x = 17 << 6 for ALL 
GLYPHS in font.

Maybe I am doing something bad by openning that TTC, because I am using 
normal  FT_New_Face call to open that font.
But TTC is a collection, what font will be choosed than?
