<request name="set_opaque_region">
<description summary="set opaque region">
This requests sets the region of the surface that contain
opaque content. The opaque region is an optimization hint for
the compositor that lets it optimize out redrawing of content
behind opaque regions. Setting an opaque region is not
required for correct behaviour, but marking transparent
content as opaque will result in repaint artifacts.
The region will be clipped to the extents of the current
surface size. Setting the region has copy semantics, and the
region object can be destroyed immediately after setting the
opaque region. If a buffer of a different size is attached or
if a nil region is set, the opaque region will revert back to
default. The default opaque region is empty.

region is the entire surface.
