[cairo] which operations modify the canvas?

I am still struggling with cairo and X11 w/ an intermediate pixmap --
XDamage generates the events, but I need to XSync explicitly,
otherwise they don't get to the window.
I think I will just call XSync when needed. For this, I need a
complete list of operations that modify the "canvas". Here is what I
have come up with (dropping cairo_):
Did I miss anything?
For future developments, it would be ideal if I could attach a
callback function to the surface or context (whichever is easier) that
would be called (with a pointer to user-suppled data) whenever actual
drawing happens. Would this be feasible?
