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.
