Noel Grandin 5357da349b Revert "remove canvas/cairo and canvas/gdi and canvas/directx backends"
So the vclcanvas backend is in worse shape than I thought. It will
take too long to get it into shape to be sure of making the next
release, so revert this for now, and I will have to find another
approach.

This reverts the following commits
