        * src/cairo-png.c (cairo_surface_write_png): Factor out bulk of
        the code into a new callback based function, write_png().  Call it
        with a stdio write callback.
        (cairo_surface_write_png_to_stream): New function to write a
        surface to a PNG stream.
        (cairo_image_surface_create_from_png): Likewise, move most of the
        code to read_png(), clean up error handling and reduce this
        function to calling read_png() with a stdio based read function.
        (cairo_image_surface_create_from_png_stream): New function to
        create an image surface from a PNG stream.

        * src/cairo-image-surface.c (cairo_image_surface_get_width)
        (cairo_image_surface_get_height): New functions to get widht and
        height of an image surface.

        * src/cairo.h: Add new prototype and error codes.

        * test/create-for-png.c (draw): Adjust to new PNG API.
