// The printing surfaces don't natively support or need
// EXTEND_PAD for padding the edges. Using EXTEND_PAD this way
// is suboptimal as it will result in the printing surface
// creating a new image for each fill operation. The pattern
// will be painted to the image to pad out the pattern, then
// the new image will be used as the source. This increases
// printing time and memory use, and prevents the use of mime
// data from cairo_surface_set_mime_data(). Bug 691061.
