[test] Add tests using each backend as a source.

Inspired by bug 7362 (painting a glitz surface onto an xlib surface
crashes cairo) and the lack of coverage for
_cairo_paginated_surface_acquire_source_image(), these tests attempt
to use each backend as a source surface for all the other backends.
For example, this checks that one can construct a PS file ready for
printing and then copy that surface to an image/xlib for previewing.
