1 2 Status of OpenGL 3.x features in Mesa 3 4 5 Note: when an item is marked as "DONE" it means all the core Mesa 6 infrastructure is complete but it may be the case that few (if any) drivers 7 implement the features. 8 9 10 Feature Status 11 ----------------------------------------------------- ------------------------ 12 13 GL 3.0: 14 15 GLSL 1.30 DONE 16 glBindFragDataLocation,
