More Tab Control fixes

[Mike Hearn]

Yep, this fixes a bug that was just annoying me 5 minutes ago with the
tab hottracking, thanks!

One more bug remaining that I can see, on multi-line tabs we don't draw
the top of the first line correctly. It can be seen in the controlspy
tab demo: http://bylands.dur.ac.uk/~mh/Tab.exe

thanks -mike
