[cairo] Freetype/OpenGL experiment

[Nicolas Rougier]

Hi all,

I've been doing some experiments for high-quality text rendering using freetype and OpenGL, inspired by technics explained at: http://www.antigrain.com/research/font_rasterization/

I think the output is now quite decent (see demo-atg-agg or demo-supixel) and maybe the gl-cairo backend may benefit from these technics (I'm not familiar enough with cairo and maybe the cairo rendering is better). Sub-pixel positioning is achieved using a dedicated shader.


All the sources/demos/screenshots are available from: http://code.google.com/p/freetype-gl/
