OpenGL.GL.ARB.texture_gather

OpenGL extension ARB.texture_gather

This module customises the behaviour of the OpenGL.raw.GL.ARB.texture_gather to provide a more Python-friendly API

Overview (from the spec)

This extension provides a new set of texture functions (textureGather) to the shading language that determine 2x2 footprint that are used for linear filtering in a texture lookup, and return a vector consisting of the first component from each of the four texels in the footprint.

The official definition of this extension is available here: http://www.opengl.org/registry/specs/ARB/texture_gather.txt
