Unit Float32 to RGBA Packing

For now this code only provides functions for float32 in range [0;1[ 1.0 is excluded from the range. The maximum number that can be stored is something like 1.0 - 1.e-7.

Full range Float32 to RGBA Packing

No functinons for now. The easier way is probably to use Unit Float32 and map it to a minValue,maxValue range.

Uint32 to RGBA Packing

Todo.
