patch for comparing test-suite output

Disabling it, as with the attached patch, makes many xlib tests pass.
It was reintroduced in commit 5bc1b1f6a, and apparently its limitations
are known.

I think that if the trade-off performance/quality is acceptable, then
tests slightly modified should see their reference images updated and
the remaining should be marked XFAIL.

Otherwise old minor differences will shadow future real bugs/artifacts.</pre>
