  1. '''OpenGL extension ARB.texture_float
  2.  
  3. Overview (from the spec)
  4.     
  5.     This extension adds texture internal formats with 16- and 32-bit
  6.     floating-point components.  The 32-bit floating-point components
  7.     are in the standard IEEE float format.  The 16-bit floating-point
  8.     components have 1 sign bit, 5 exponent bits, and 10 mantissa bits.
  9.     Floating-point components are clamped to the limits of the range
  10.     representable by their format.
  11.     
  12.  
  13. The official definition of this extension is available here:
