- See my message to this guy where I give a few examples which make planar look

- I think that Chunky can still do that better. Most Chunky cards have got a
- 16-color mode where 1 byte represents 2 16-color pixels. Although lots of
- advantages of Chunky are lost this way it would still be faster to plot a
- pixel, draw a vertical line and stuff like that vs 4 bitplane Planar.
