-// gdk_cairo_set_source_pixbuf(), CairoCachedSurface assumes that the pixbuf is
-// immutable after UsePixbuf() is called and can be sent to the X server
-// once. From then on, that cached version is used so we don't upload the same
-// image each and every time we expose.
-//
-// Most cached surfaces are owned by the GtkThemeProvider, which associates
-// them with a certain XDisplay. Some users of surfaces (CustomDrawButtonBase,
-// for example) own their surfaces instead since they interact with the
-// ResourceBundle instead of the GtkThemeProvider.
