[cairo] RFC: introduce cairo_surface_get_height() / width()

Hi folks,

retrieving surface dimensions currently only works by surface-type
specific functions, which isn't particularily good encapsulation.

For example, in my widget toolkit, which shall be able to render
onto any surface type, I need to do special tweaks for getting
the surface dimensions.

So, should we introduce generic functions (and corresponding
backend ops) for that ?
