This is actually the reason, why I have not followed-up yet. It is not
straightforward to do pattern fills with metapost. I think one needs to draw the
patterns (generate metapost code to do it) and then clip the to the box. So the
first thing is to get the patterns. Where can I get the patterns that are
supposed to be supported? Is it only boxes that we need to support with patterns?

I have noticed also another difference. The grid lines are solid in metapost
output and dashed (dotted?) in postscript output. Shall I look into making those
the same?

I think it is better to have consistent colors, although I find metapost driver
colors much, much, much, oh so much, more appealing than postscript colors (at
least the first 8). Since metapost supports RGB colors I think it should be easy
to get exactly the same colors in both drivers (all 64 AFAIR). I hope that
current metapost colors are among these.
