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). | |
