- ddfstrt and ddfstop are best aligned to 64 pixels.
- - the chipset needs 64+4 horizontal pixels after the DMA start before the
- first pixel is output, so diwstrt_h = ddfstrt+64+4 if you want to
- display the first pixel on the line too. Increase diwstrt_h for virtual
- screen panning.

+ virtual screen panning.
- the display DMA always fetches 64 pixels at a time (fmode = 3).
- - ddfstop is ddfstrt+#pixels-64.
- - diwstop_h = diwstrt_h+xres+1. Because of the additional 1 this can be 1
