+         *    minFractionRendered: Lower bounds on fraction of pixels that

+         *    stabilityThresholdMs: A time that alpha and fraction rendered
+         *    must remain within bounds before we can "enter the state"
+         *
+         * The fraction of pixels rendered is a computation based on scale, crop
+         * and occlusion. The calculation may be somewhat counterintuitive, so we
+         * can work through an example. Imagine we have a layer with a 100x100 buffer
+         * which is occluded by (10x100) pixels on the left, and cropped by (100x10) pixels
+         * on the top. Furthermore imagine this layer is scaled by 0.9 in both dimensions.

+         *      o x x x
+         *      o x x x
+         *
+         * We first start by computing fr=xscale*yscale=0.9*0.9=0.81, indicating
+         * that "81%" of the pixels were rendered. This corresponds to what was 100
+         * pixels being displayed in 81 pixels. This is somewhat of an abuse of
+         * language, as the information of merged pixels isn't totally lost, but
+         * we err on the conservative side.
+         *
+         * We then repeat a similar process for the crop and covered regions and
+         * accumulate the results: fr = fr * (fractionNotCropped) * (fractionNotCovered)
+         * So for this example we would get 0.9*0.9*0.9*0.9=0.65...
+         *
