- '''OpenGL extension ARB.shadow
-
- Overview (from the spec)
-
- This extension clarifies the GL_SGIX_shadow extension.
-
- This extension supports comparing the texture R coordinate to a depth
- texture value in order to produce a boolean texture value. This can
- be used to implement shadow maps.
-
- The extension is written in generic terms such that other texture
- comparison modes can be accomodated in the future.
-
- The official definition of this extension is available here:
- http://oss.sgi.com/projects/ogl-sample/registry/ARB/shadow.txt
-
