Hi Sam,

20100815_1.diff contains updates for the directfb driver:

- more documentation, mainly on software OpenGL in README.directfb
- Revised error handling leading to leaner code
- Improved/fixed OpenGL handling of multiple contexts.
- Made the built-in simple window manager handle OpenGL windows.
- Rewrote pixelformat mapping - this was quite ugly before.

Well, all software GL, but working :-)
