Sure.  That's all I want too -- in this case the entity using Render is cairo, 
so it would make sense for cairo to do this.

Or are you suggesting that any cairo consumer suffering from performance issues 
due to Render should write their own separate cairo surface implementation and 
use it instead of cairo_xlib_surface?  That doesn't seem like the way to go...
