cc: Translate the canvas to correctly detect solid colors

cc: Translate the canvas to correctly detect solid colors

While animating the transition, the origin is off in outerspace, as a
result we weren't correctly detecting the layer as non-solid since
the bitmap wasn't in the viewport

Also wrote a test for this.
