* Color, depth, stencil packing functions.
* Used to pack basic color, depth and stencil formats to specific
* hardware formats.
*
* There are both per-pixel and per-row packing functions:
* - The former will be used by swrast to write values to the color, depth,
* stencil buffers when drawing points, lines and masked spans.
* - The later will be used for image-oriented functions like glDrawPixels,
* glAccum, and glTexImage.
