Use pixel coordinates for shadow underlay bounds

Use pixel coordinates for shadow underlay bounds

* Introduced new request set_rectangular_surface_shadow.
Reprecated old one.

* Added placeholder for set/unset moving introduced in remote_surface version 2.

This only switches the underlay to pixel and that looks good enough to me.
I'll work on the shadow itself separately if necessary.

BUG=687742
TEST=tested on Elm.
