1162+ * geometry, so the client should avoid putting functional elements
1163+ * outside of it.
1164+ *
1165+ * The window geometry is double-buffered state, see wl_surface.commit.
1166+ *
1167+ * When maintaining a position, the compositor should treat the (x, y)
1168+ * coordinate of the window geometry as the top left corner of the window.
1169+ * A client changing the (x, y) window geometry coordinate should in
1170+ * general not alter the position of the window.

1172+ * Once the window geometry of the surface is set, it is not possible to
1173+ * unset it, and it will remain the same until set_window_geometry is
1174+ * called again, even if a new subsurface or buffer is attached.
1175+ *
