pdf: combine source and mask images into single image
Since PDF stores the alpha component of images in a separate stream
which can have a different resolution and encoding to the color
components we can optimize the case where the source and mask are both images.
If the source and mask are both images with the same extents and the
source is opaque, combine the images into a single PDF image (ie the
source is written the the image stream and the mask is written to the
smask stream).
