[Mesa-dev] [PATCH 1/2] glsl: Expose built-in packing functions under GLSL 4.2.

[Matt Turner]

ARB_shading_language_packing is part of GLSL 4.2, not 4.0 as I
mistakenly believed. The following functions are available only with
ARB_shading_language_packing, GLSL 4.2 (not GLSL 4.0), or ES 3.0:

   - packSnorm2x16
   - unpackSnorm2x16
   - packHalf2x16
   - unpackHalf2x16
