 * 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.
