Remove destroy_closure argument from cairo_pdf_surface_create_for_stream. Rename width,height to width_in_points, height_in_points for better clarity. Brush a bunch of dust off of the PS backend and bring it up to date with the latest API conventions from the PDF backend. These include: accepting a filename rather than a FILE in the primary constructor, providing a stream-based interface for more flexibility, and accepting a surface size in device-space units (points) rather than inches. Make it a little more clear that the width and height being passed around are in units of points. Update to the latest cairo-ps.h changes as described above. Notice how much more sane things become now that the surface size is described in device-space units.
