[... patch code deleted ...]

Yes, I confirm that is the patch code I am testing, back edited to my
working environment (So far, I call this "peter35").

Some more test results are attached as PNG files and tests will
continue for at least another couple of days. I can comment
further on the "finally close this issue" question then, but it
looks very good so far.

Unless I find some issue, I won't push further results to this list,
But results can be pulled from [1].
