Opal lives at svn://svn.gna.org/svn/gnustep/libs/opal/trunk and there
are some examples in the ./Tests directory. Ideally, I think, you would
want to avoid copying the pixel data from the cairo surface to an OpenGL
textzre but instead use a cairo surface that can be bound to an OpenGL
texture using EGL. This has the upside that it would also, with little
tweaks, work with OpenGL/ES (i.e. on mobile platforms) and it would give
optimal performance.
Cheers,
