Very slowly - it's nice to be able to do this, but after experimenting
with it a bit I think it's more useful to either get a real Windows
version of something, or run it full-screen (with or without Windows)
if it does significant graphics.  It's a really significant performance
hit - I don't recall the exact figures, but some friends of mine and I
timed it at something around a factor of 10 (!) for a fairly simple
graphics program.  It's adequate for incidental graphics but hardly
for production work (maybe on a 50 MHz 486 ...)
