| * 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 stil functions well as a manual testcase (with either |
| * the "-show" or "-dump" options). |
