No need to lock or copy.

ppm_save() uses the pixman image (surface->image) only anyway, so
changing it to accept a pixman image instead of the surface is easy.

pixman images are reference counted, so you can just grab a reference
using pixman_image_ref() and run with it, without risking it'll be
released underneath your feet, then unref when done.

cheers,
  Gerd
