Yes, I agree. For now I losened the always failing test 7 gd2 case. And I display the libgd version along with the failing tests. To be able to generate those cases. The other tests are only really useful for regression testing, but are not run by any tester. -- Reini Urban

I loosened the regressions test failures, and when you try the other formats, it will be TODO. This should do it to test the libgd compare API -- Reini Urban
