ui can get screwed up when switching contexts

[stripedpajamas]

there seems to be an issue with diffy when the messages array gets drastically filtered (switching between public and private contexts). I filed an issue with mafintosh and in the meantime tried to workaround by having scat only fill up ~75% of the screen, but i'm not sure if the workaround is working around too well.

Trashed the 75% thing and did some math magic to keep messages from overflowing and causing the weird Diffy glitch. I don't think Diffy cares about what's off the top of the screen and that's what was screwing up the UI. 196f029

@stripedpajamas hey did your math magic fix the ui glitches you were seeing? i'm having similar issues with cabal :)

hi @cblgh :) yeah the math magic fixed it! or at least it was a better work around. it seemed like the glitch was whenever i had too much content to fit on one terminal screen, diffy would kind of not work very well. i couldn't ever figure out how to make diffy play nice, so i ended up determining how many lines the chat messages (including word wraps when applicable) would take up, and then filtering my message list to only show x number of messages -- so my content always fits on one terminal screen. and then to allow scrolling up into previous messages, i added listeners to page-up/page-down to move the message view-- but never showing more than a terminal screen can handle. and that kept diffy v happy.

@stripedpajamas thanks for the response!

i'll see if we can find the right mathemagic to fix this in cabal (or even fix it upstream in diffy... hmmmmm)
