We still need a way to get something surface-specific to show the overlay. After
talking with alexst, we think the best approach is to add a "virtual
gfx::AcceleratedWidget GetAcceleratedWidget()" function here. You can add it in
here or I can upload another CL when this goes in

Not sure but it seems like it would be more appropriate to get to whatever
surface specific handle you need at a lower level from within the ozone
implementation of ScheduleOverlayPlane. If you actually need  some addition to
the GLSurface API then let's do that separately.
