Support for fill patterns/thatching

[Lord-Kamina]

First, let me say I just found this today and at least at first glance, it's looking leaps and bounds better than the original.

That said, at some point I forked the original and added a "Want to try" option that didn't have a color but rather a diagonal thatching pattern (done in html5 I think but can't remember for sure). I realize this one supports adding any number of extra options OOB (awesome!) but I was wondering whether you could add support for thatching patterns or at least maybe a few predetermined ones?
