'''OpenGL extension APPLE.texture_range

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

Overview (from thespec import 
  
  This extension provides a method to specify the range of client address
  space that may be used by a texture.  In general, the storage size of a
  texture may be easily determined by the texture's data type and geometry.
  However, driver optimizations may be realized if an extended address
  range is specified to encompass the storage of multiple textures, or to
  encompass potential future changes in the size of a texture.  A typical
  usage of this extension is to specify an identical address range for
  several textures in a particular working set that encompasses the storage
  of all the textures in the set.  This allows the driver to make a single
  memory mapping for all of the textures.
  
  Further, a mechanism is provided to allow the application to give the GL
  driver a hint regarding the storage requirements of the texture data.

The official definition of this extension is available here:
