Rewrite scrollable layers using multiple layers.
Remove PlatformBridge::updateLayers and instead call layersDraw from
ChromeClientAndroid during a requested sync.
Instead of LayerAndroid having knowledge of scrolling pictures, use multiple
layers (background, mask, foreground).
Update navigation to use the new structure. Always record nodes in absolute,
unscrolled coordinates. Do not track layers unless the node has a composited
layer and a last child. Check for composited parents when adding to tracked
layers as well.
TODO:
* developer.android.com doesn't completely work with navigation due to some
nodes being clipped out.
* BaseLayerAndroid needs to be able to operate with a matrix other than
identity.
* nested fixed position elements do not draw correctly.
* nested overflow layers haven't been tested.
