* cairo_xcb_surface_set_size:

* @width: the new width of the surface
* @height: the new height of the surface
*
* Informs cairo of the new size of the XCB drawable underlying the
* surface. For a surface created for a window (rather than a pixmap),
* this function must be called each time the size of the window
* changes. (For a subwindow, you are normally resizing the window

* A pixmap can never change size, so it is never necessary to call
* this function on a surface created for a pixmap.
*
* If cairo_surface_flush() wasn't called, some pending operations
* might be discarded.
