ike-draw

So my brother has been working on some new methods for ```MOAIDraw```.  They're kind of cool.  He's still working on them, and especially on cleaning them up, but I'd like to get what he has into Moai so we can start using them in our games.  :cherry_blossom: 

If you see obvious mistakes in here, it might be better just to comment directly on https://github.com/IkeBart/moai-dev/commits/ike-draw , since he can actually see that repo.  Everything in this PR is just cherry-picked from there anyway.  :cherries: 

Once this gets merged, you'll need to merge https://github.com/mindsnacks/Ahu/pull/296 to support the changes to ```MOAIColor```.  :art:
