I don't know if this would make sense in a wider perspective, but a
registering a callback function (a `hook') that would be called
whenever a surface changes (ie is drawn on) would be nice, especially
for X11 surfaces.

At the moment, in the Common Lisp interface cl-cairo2 I keep track of
operations that change the surface (fill, stroke, etc) and call this
callback function each time, but if more operations show up that
change a surface, this could become tedious to maintain.
