+/**
+ * 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).
