'''OpenGL extension SGIS.texture_filter4
This module customises the behaviour of the
OpenGL.raw.GL.SGIS.texture_filter4 to provide a more
Python-friendly API
Overview (from the spec)
This extension allows 1D and 2D textures to be filtered using an
application-defined, four sample per dimension filter. (In addition to
the NEAREST and LINEAR filters defined in the original GL Specification.)
Such filtering results in higher image quality. It is defined only
for non-mipmapped filters. The filter that is specified must be
symmetric and separable (in the 2D case).
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/SGIS/texture_filter4.txt
