Yes.   But your expose-area is restricted by at
current viewport size, at least.  Why don't you simply
allocate a transient surface instead of a transient
pixmap and set that as the current target surface to
the cairo_t you pass to the user's expose cb?

To handle expose events your users must only implement
the expose() callback to re-draw the szene located at
(event.x=55537, event.y, event.width, event.height)
onto a cairo_surface located at (0, 0, event.width,

Why is that a problem?
