Markus Stange 64c13fc106 Bug 1587940 - Remove capability for opaque regions from NativeLayer interface. r=jrmuizel
This change makes opaqueness a boolean per layer again. The opaque region is
currently only used by the temporary WebRender code; the future WebRender code
won't use it. Removing this support simplifies the code and makes it easier to
implement clipping.
