  43 * Interpretation of offset for color fields: All offsets are from the right,
  44 * inside a "pixel" value, which is exactly 'bits_per_pixel' wide (means: you
  45 * can use the offset as right argument to <<). A pixel afterwards is a bit
  46 * stream and is written to video memory as that unmodified.
  47 *
  48 * For pseudocolor: offset and length should be the same for all color
  49 * components. Offset specifies the position of the least significant bit
  50 * of the pallette index in a pixel value. Length indicates the number
  51 * of available palette entries (i.e. # of entries = 1 << length).
