use a much stronger binding to our specific freeimage that works reliably on linux. previously it didn't and the tests covering freeimage support were just being skipped as they assumed it to be disabled. once the binding works it reveals slight breakage in the tests themselves, fixed with an upstream patch. this breakage was already revealing itsef on darwin as the freeimage binding was "working" there.
