xcb: Add an assert for the tighten-bounds test
This code casts the result of _cairo_xcb_surface_create_similar() to
cairo_xcb_surface_t*. However, the tighten-bounds test makes this run with
bounded extents of size 0x0 and thus _cairo_xcb_surface_create_similar() falls
back to an image surface. Ugly.
