'''OpenGL extension ARB.fragment_shader
Overview (from the spec)
This extension adds functionality to define fragment shader objects. A
fragment shader object is a shader object (see the ARB_shader_objects
extension) that, when attached to a program object, can be compiled and
linked to produce an executable that runs on the fragment processor in
OpenGL. The fragment processor is a programmable unit that replaces the
OpenGL 1.4 fixed-function texturing, color sum and fog stages. This
extension also defines how such an executable interacts with the fixed
functionality fragment processing of OpenGL 1.4. The language used to
write fragment shaders is not discussed here. That language is defined
in the OpenGL Shading Language specification as the Fragment Shading
Language.
The official definition of this extension is available here:
