Couriersud to Sam 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 :-)
