Re: Rotated text

[Dov Grobgeld <dov imagic weizmann ac il>]

Have a look at paps at:

    http://imagic.weizmann.ac.il/~dov/freesw/paps/

It shows you how to extract the freetype2 glyphs from a pango layout.
Rendering the glyphs at an angle should be pretty straightforward 
through the freetype2 API.
