text: '''OpenGL extension ARB.shading_language_packing
  
  This module customises the behaviour of the 
  OpenGL.raw.GL.ARB.shading_language_packing to provide a more 
  Python-friendly API
  
  Overview (from the spec)
  	
  	This extension provides the GLSL built-in functions to convert a 32-bit
  	unsigned integer holding a pair of 16-bit floating-point values to or from
  	a two-component floating-point vector (vec2).  
  	
  	This mechanism allows GLSL shaders to read and write 16-bit floating-point
  	encodings (via 32-bit unsigned integers) without introducing a full set of
  	16-bit floating-point data types.
  	
  	This extension also adds the GLSL built-in packing functions included in
  	GLSL version 4.00 and the ARB_gpu_shader5 extension which pack and unpack
  	vectors of small fixed-point data types into a larger scalar. By putting
  	these packing functions in this separate extension it allows
  	implementations to provide these functions in hardware that supports them
  	independent of the other ARB_gpu_shader5 features.
  	
  	In addition to the packing functions from ARB_gpu_shader5 this extension
  	also adds the missing [un]packSnorm2x16 for completeness.
