/**
|
|
* 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).
