This diff was an earlier one with some debug printfs in so you can see how
the tuning knobs work.  I was only keeping an eye on a young computer user's
activities so ignored small screen changes and wrote out the stills to lossy
jpegs with libjpeg.  If you plan on saving screens no matter if there are
changes or not then I'd throw away all the g_bitmap_data_last_write stuff.

diff is against rdesktop-1.6 with whatever patches are in ubuntu 9.04
jaunty.  Added libjpeg62-dev in addition to the regular rdesktop build
dependencies.  Have fun and thanks for letting me know what you end up with.

~ Daniel
