Can you explain what you want to achieve in more detail?
With 2.5D I always understood having multiple flat layers stacked on
top of eachother. This is of course exactly what Cairo does.

If you want a perspective transform (which is not affine), then that's
currently not possible to do with Cairo. It is possible in pixman and
I proposed some patches to cairo to expose that functionality, but
those where met with complaints about the API. I haven't revisited
