I've tested both versions, and the output looks pretty similar. You can
see for yourself again: http://home.rochester.rr.com/specht/test

The image is sharper than the results from yesterday, but still about

I really appreciate the time you are putting in to fix this stuff. ... and =
I'm
really sorry that the turnaround times are so long right now, but my wife is
in the hospital, and there are just more important things to do than to hack
on some software project ...=20
