This mechanism allows GLSL shaders to read and write 16-bit floating-point encodings (via 32-bit unsigned integers) without introducing a full set of 16-bit floating-point data types. This extension also adds the GLSL built-in packing functions included in GLSL version 4.00 and the ARB_gpu_shader5 extension which pack and unpack vectors of small fixed-point data types into a larger scalar. By putting these packing functions in this separate extension it allows implementations to provide these functions in hardware that supports them independent of the other ARB_gpu_shader5 features. In addition to the packing functions from ARB_gpu_shader5 this extension also adds the missing [un]packSnorm2x16 for completeness.
