* REMIND: This testcase was originally intended to automatically compare
* the results of the software BufferedImageOp implementations against
* the OGL-accelerated codepaths. However, there are just too many open
* bugs in the mediaLib-based codepaths (see below), which means that
* creating the reference image may cause crashes or exceptions,
* and even if we work around those cases using the "-ignore" flag,
* the visual results of the reference image are often buggy as well
* (so the comparison will fail even though the OGL results are correct).
* Therefore, for now we will run the testcase with the "-ignore" flag
* but without the "-compare" flag, so at least it will be checking for
* any exceptions/crashes in the OGL code. When we fix all of the
* outstanding bugs with the software codepaths, we can remove the
* "-ignore" flag and maybe even restore the "-compare" flag. In the
* meantime, it also functions well as a manual testcase (with either
* the "-show" or "-dump" options).
