Robert Carr 354c56590e View: Expose gatherTransparentRegion
Recently exposed ViewRoot API requires requestTransparentRegion for
many of the use cases we want to support. requestTransparentRegion is
already public API, however the documentation and definition is a little
confusing and arguably it shouldn't do anything unless we also implement
gatherTransparentRegion. gatherTransparentRegion is already made public
through SurfaceView, and so exposing it properly on View seems like
a non disruptive option.

Test: android.view.cts.ViewRootSyncTest
