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).
