- * 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.
