+        This request sets the region of the surface that contains visible content.
+        Visible content refers to content that has an alpha value greater than zero.
+
+        The visible region is an optimization hint for the compositor that lets it
+        avoid drawing parts of the surface that are not visible. Setting a visible region
+        that does not contain all content in the surface may result in missing content
+        not being drawn.
+
+        The visible region is specified in buffer-local coordinates.
+
+        The compositor ignores the parts of the visible region that fall outside of the surface.
+        When all parts of the region fall outside of the buffer geometry, the compositor may
+        avoid rendering the surface entirely.
+
+        The initial value for the visible region is empty. Setting the
+        visible region has copy semantics, and the wl_region object can be destroyed immediately.
+        A NULL wl_region causes the visible region to be set to empty.
