Revamped component action animation support so that we're not passing

around arrays of multi-frame images but instead pass around one object
that knows how to render any action frame in any orientation. This
apparently fixed some horrible bug that we had introduced in doing JITC
and now the whole thing is super fast, just like I always thought it would
be. Once we introduce trimmed images, it will blaze!
