Started to integrate Color.js; it's having trouble parsing user-entered values though.
nvm... my bad.  Color.js works perfectly, so brightness slider now does as well.
(somewhat) Fixed the transparency of sketch lines.
FINALLY CHANGED BRUSH/ACTION MODEL!  Gawd that was a lot of work...
Frame history now works, redraws should be much faster.
Fixed action history, it really should be faster now.
Added a little bit of commentary to the code, probably not a good substitute for a full explanation, but I think it'll help.
Merge branch 'master' of github.com:Pholey/Whiteboard into taystack-chaplin-grunt
