Emits the current page for backends that support multiple pages, but
doesn't clear it, so, the contents of the current page will be retained
for the next page too. Use cairo_show_page() if you want to get an
empty page after the emission.
This is a convenience function that simply calls
cairo_surface_copy_page() on cr's target.
