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