OpenGL extension ATI.pixel_format_float
Overview (from the spec)
This extension adds pixel formats with floating-point RGBA color
components.
The size of each float components is specified using the same
WGL_RED_BITS_ARB, WGL_GREEN_BITS_ARB, WGL_BLUE_BITS_ARB and
WGL_ALPHA_BITS_ARB pixel format attributes that are used for
defining the size of fixed-point components. 32 bit floating-
point components are in the standard IEEE float format. 16 bit
floating-point components have 1 sign bit, 5 exponent bits,
and 10 mantissa bits.
In standard OpenGL RGBA color components are normally clamped to
the range [0,1]. The color components of a float buffer are
clamped to the limits of the range representable by their format.
