Detailed Description

Represents numbers on [0, 1] in 16 bits as an unsigned normalized 0.8 fixed-point value using the same encoding scheme as OpenGL.

Note that arithmetic operations may over and under-flow, just like uint16 arithmetic.

OpenGL specifications can be found here: http://www.opengl.org/registry/specs/ARB/shading_language_packing.txt
