| '''OpenGL extension ARB.ES2_compatibility |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.ARB.ES2_compatibility to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension adds support for features of OpenGL ES 2.0 that are |
| missing from OpenGL 3.x. Enabling these features will ease the process |
| of porting applications from OpenGL ES 2.0 to OpenGL. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/ARB/ES2_compatibility.txt |
