Tony,
I have integrated the X11 drivers into the Microwindows
codebase, and have found them very useful. Thanks.
I did find, for some strange reason, that the rgb values in
the PIXELVAL_to_pixel routine to _still_ be reversed
in the 16 bit PF_TRUECOLOR565 mode though, so I
reversed them and now the colors are completely correct.
I've also solved the XFlush() problem (that of not completing
all Xlib i/o before hanging on our select()) by extending the
driver interface to include a scrdev.PreSelect() call that
is called (guess) before the main loop select(). Dan
had contributed a patch to this but it involved #including
X11 in the device-independent main loop.
There's one other annoyance that I haven't solved:
Your driver waits for a FocusIn event before installing
the colormap, with the result that the microwindows
display is incorrect right after running it, until the mouse
is moved. I tried changing this to Expose, with no
effect. Isn't there another event we can wait for,
or install the Colormap right after MapWindow?
I'm going to place the modifed scr_x11.c file on my ftp server,
the XFlush() part won't work until 0.87 is released,
but the color code is better.

I should have 0.87 out here early this week.
