Unbelievable! That's the *second* time I've written a Microwindows/Nano-X
screen driver and it's worked without having any hardware to run it on!!! Also
big thanks to Jacob for sending me his sample Hercules code, which was very
easy to understand.

Uh-oh. Scratch the above comment. You mean that it took
10 minutes to *draw* the screen! (laughing in background, peers looking
at me very strangely...) Well, we definitely need that HERC_drawhline
to be implemented, because now it calls HERC_drawpixel for *every* pixel
on the screen, all 252,000 of them. I can take a hack at rewriting that,
but It'd be nice if someone with a card did it. The file is
mwin/src/drivers/scr_herc.c.

The problem is definitely in HERC_drawhline. Rewrite it to
draw the horizontal line directly, rather than call HERC_drawpixel.
