But this is a major problem of magicpoint. I recently did a presentation
on a fair and expected the resolution of the beamer to be 1024x768.
It could only handle 800x600 and I had to heavily adjust my slides...

I admit, I did never look in the mgp code, but if this is just a
off by one error (IMHO it happens too frequently for that...) -
what about scaling/cropping the text-bitmap before you put it
on screen?
