25 # OpenGL Core and Compatibility context support
27 OpenGL 3.1 and later versions are only supported with the Core profile.
28 There are no plans to support GL_ARB_compatibility. The last supported OpenGL
29 version with all deprecated features is 3.0. Some of the later GL features
30 are exposed in the 3.0 context as extensions.
