I have altered the vga_flushrect() code in DRAW.C of devg-vga.so
to rotate the display clockwise90,
but the problem is that it does not refresh. Obviously, it is refreshing
another part of the display instead of the part that I indent.
Should I also altering some other part of the code, or am I simple
going about it the wrong way?

Here’s a hint: you’ll need to swap the x and y parameters
to io-graphics, e.g. -g480x640. Also, alter the set_mode and
get_modeinfo entry points, to work with 480x640 instead of 640x480.
In any case, there will be a display rotation module in the next
Beta release, which should work with any driver.
Thanks for the hint. I would have never thought of that.
Would I be pushy if I asked when the beta release is coming?
