These tests failed on some slaves (AFAIR on x86 hosts). I think it is
due to the floating point issues, either computation errors or
float-to-integer conversion. Actually I don't know what to do about
that. Threshold is 1.0 for byte data type, so it means that we are
having seriously different warping results on different hosts.

At least these tests can be used locally when working with warping code.
