| '''OpenGL extension SGIX.shadow | |
| This module customises the behaviour of the | |
| OpenGL.raw.GL.SGIX.shadow to provide a more | |
| Python-friendly API | |
| Overview (from the spec) | |
| This extension defines two new operations to be performed on texture | |
| values before they are passed on to the filtering subsystem. These | |
| operations perform either a <= or >= test on the value from texture | |
| memory and the iterated R value, and return 1.0 or 0.0 if the test | |
| passes or fails, respectively. | |
| The official definition of this extension is available here: | |
| http://www.opengl.org/registry/specs/SGIX/shadow.txt | |
