'''OpenGL extension SGIS.sharpen_texture
This module customises the behaviour of the
OpenGL.raw.GL.SGIS.sharpen_texture to provide a more
Python-friendly API
Overview (from the spec)
This extension introduces texture magnification filters that sharpen
the resulting image by extrapolating from the level 1 image to the
level 0 image. Sharpening can be enabled for all color channels, for
the alpha channel only, or for the red, green, and blue channels only.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/SGIS/sharpen_texture.txt
