[cairo] surface matrix semantics?

I'm a little unclear on how matrix transforms on surfaces are being 
applied -- it seems that when I apply a matrix to a surface, and then 
use that surface as a pattern, the visible result I get is the inverse 
of the matrix that I applied, which is not what I'd expect.  Are the 
matrices on surfaces intended to transform surface-local coordinates to 
world coordinates?  Or to transform world to surface-local?
