Native bindings to the ARB_fragment_shader extension.

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 is defined in the OpenGL Shading Language specification as the Fragment Shading Language.

Promoted to core in OpenGL 2.0.
