(* Formats
 * Most of these names have the following convention:
 *      A = Alpha
 *      R = Red
 *      G = Green
 *      B = Blue
 *      X = Unused Bits
 *      P = Palette
 *      L = Luminance
 *      U = dU coordinate for BumpMap
 *      V = dV coordinate for BumpMap
 *      S = Stencil
 *      D = Depth (e.g. Z or W buffer)
 *      C = Computed from other channels (typically on certain read operations)
 *
 *      Further, the order of the pieces are from MSB first; hence
 *      D3DFMT_A8L8 indicates that the high byte of this two byte
 *      format is alpha.
 *
 *      D16 indicates:
 *           - An integer 16-bit value.
 *           - An app-lockable surface.
 *
 *      All Depth/Stencil formats except D3DFMT_D16_LOCKABLE indicate:
 *          - no particular bit ordering per pixel, and
 *          - are not app lockable, and
 *          - the driver is allowed to consume more than the indicated
 *            number of bits per Depth channel (but not Stencil channel).
