[cairo] Add get_width()/get_height() to pycairo svg surfaces

I think all the specialized surfaces should have a get function for 
anything that can be set on them. If there is a surface type xyz with 
these functions:

	cairo_xyz_surface_create(bling, level, dimensions)
	cairo_xyz_surface_set_twiddle_factor(surface, value)

Then these functions should exist:


This does mean that some surfaces will have to keep around a copy of 
data that it otherwise does not need after the surface is created. 
However I think in most cases this is minor and it is better than the 
user having to keep them in parallel variables.

This would mean the get_width methods described below would exist. It 
also means you could retrieve everything about the X11 surface such as 
the visual.
