show_surface() is going away ...
It's basically already that way as far as the backend interface is
concerned ... the code creates a temporary pattern before calling
into the backend.
You do want to make sure that you use a matrix for your surface pattern
that is exactly the identity except for translations when possible,
since that enables a lot of optimization that can't be otherwise done.
