3. Command Parameters
DXn, DYn (n = 1 to 4): Rendering coordinates (absolute coordinates). Negative numbers
expressed as two's complement.
Color:
8- or 16-bit/pixel color specification. For 16-bit/pixel drawing, the
color specification should match the destination pixel format.
For 8-bit/pixel drawing, the same value should be set in the upper and
lower bytes.
