We've had the cairo_image_surface_create functions since before any
PNG code landed in cairo. The cairo_png_surface was just a convenience
around the cairo_image_surface stuff, making it simpler to write PNG

But, we've come up with a better approach for that convenience, which
is to just use cairo_image_surface, (or any other surface for that
matter), and then call cairo_surface_write_png. So cairo_png_surface
no longer exists in cairo as of what's in the latest version in CVS.
