Automate error checking for fallback-resolution.

For this we extend the boilerplate get_image() routines to extract a
single page out of a paginated document and then proceed to manually
check each page of the fallback-resolution test.

(Well that's the theory, in practice SVG doesn't support multiple pages
and so we just generate a new surface for each resolution. But the
infrastructure is in place so that we can automate other tests,
e.g. test/multi-pages.)
