If this is going to be done, maybe we should implement the entire NeWS 
interface, where a surface is created using the current transformation and 
clipping path. The above would be accomplished by making a rectangle path at 
x,y,width,height and then doing cairo_surface_create(ct).

However I don't understand why GTK can't just do 
cairo_translate(ct,-event.xoff,-event.yoff) before calling the widget drawing
