OpenGL extension ARB.half_float_pixel
This module customises the behaviour of the
OpenGL.raw.GL.ARB.half_float_pixel to provide a more
Overview (from the spec)
This extension introduces a new data type for half-precision (16-bit)
floating-point quantities. The floating-point format is very similar
to the IEEE single-precision floating-point standard, except that it
has only 5 exponent bits and 10 mantissa bits. Half-precision floats
are smaller than full precision floats and provide a larger dynamic
range than similarly sized normalized scalar data types.
This extension allows applications to use half-precision floating-
point data when specifying pixel data. It extends the existing image
specification commands to accept the new data type.
Floating-point data is clamped to [0, 1] at various places in the
GL unless clamping is disabled with the ARB_color_buffer_float
