rdesktop/cache.c
Matt Chapman e11a571f14 Committing some awesome progress I made while overseas - this commit
really embodies a huge number of changes. We are now able to talk quite
fluently to a French NT Terminal Server - in normal usage only minor
font issues remain (handling of TEXT2 order is not perfect).

The next major hurdle is encryption, and it will be quite a big hurdle
- there seems to be some quite nasty session key stuff.
