* Pixels are written according to physical vram. Foreground low byte is for physical VRAM0. Background low bytes is for physical VRAM 1. Foreground high byte is for physical VRAM1, and background high byte is for physical VRAM 1.
* To draw a font in the same colour ensure the same colour is repeated for all pixels in FC and BC (i.e. for 8 bit mode set FC upper and lower byte to the same, and set BC upper and lower byte to the same.)
* For LOP, SC comes from background colour or foreground colour depending on the value of the bit.
