SRGB & FLOATING POINT REPRESENTATION SRGB & FLOATING POINT REPRESENTATION
Some srgb-related code in this library relies on floats being 32-bit The sRGB functions presume IEEE floating point. If you do not have
IEEE floating point, and relies on a specific bitpacking order of C IEEE floating point, define STBIR_NON_IEEE_FLOAT. This will use
bitfields. If you are on a system that uses non-IEEE floats or packs a slower implementation.
C bitfields in the opposite order, then you can use a slower fallback
codepath by defining STBIR_NON_IEEE_FLOAT. (We didn't make this choice
idly; using mostly-but-not-100%-portable-code for this is a massive
speedup, especially upsampling where colorspace conversion dominates.)
