Merge branch 'master' into createjs-rendering
Added preliminary support for a custom hitArea for mouse/touch input.
Force the hitArea to use an initial fill so it's not transparent.
Had to move hitArea setup to after this.container is created.
Saving rendered hitAreas so they're reusable instead of generating innumerable identical shapes.
Merge branch 'createjs-rendering' into example-rendering
Added render-image scene with a few tests. Masks are not currently set up correctly.
