That's a bit unfortunate, but it does make things easier. The only thing
I could really think of was counting the non-zero pixels in some area
(regardless of their exact position) and checking that the count is
greater than some threshold, which is pretty obtuse and probably worse
than nothing.

I'll send another patchset with the fragile parts of the test removed
shortly.
