------------------------------------------------------------------
The last change is based on some of the "alt1" patch. BTW the Andreas "dirty hack" was pretty good too (when using the translation changes only) but the other change was even better.
Improved:
- 007087-payment-due-p1.pdf: better: shadow now visible
- gs-bugzilla691218.pdf: better: prices now visible
- gs-bugzilla692160.pdf: probably OK, shadows at correct position
- PDFBOX-1451.pdf: shadows now visible
- ***755: OK, shadows at correct position now
- ***417: different color
- K_UPMEYER_SPRING10.pdf: OK, shadow visible
- PDFBOX-1691-FORIS-HV.pdf: OK, shadow visible
- PDFBOX-994.pdf: green is back
- PDFBOX-2103.pdf: OK
- PDFBOX-2495.pdf: OK, shadows visible
- PDFBOX-2658.pdf: OK, top right now good
- PDFBOX-2950.pdf: OK, shadows visible
- PDFBOX-3118.pdf: OK, shadows visible
- PDFJS-3370-p19.pdf: OK, shadows visible
- PDFJS-5853.pdf: people slightly visible
- PDFJS-5811-2.pdf: better
- PDFJS-4735.pdf: better in half the space
- PDFJS-3370-p19.pdf: shadows back
- PDFJS-5811-2.pdf: much improved, p5 still a problem
- PDFJS-5853.pdf: faces somewhat visible again, as in rev 1633496
Differently bad:
- bugzilla-852992.pdf
- evince-bug431088.pdf
- gs-bugzilla688601.pdf
- gs-bugzilla692217.pdf
- PDFBOX-1416.pdf
- PDFJS-3096.pdf
- PDFJS-4735.pdf
- PDFJS-5526-p11-13.pdf
- PDFBOX-1870-technical_v2_p9.pdf
I've also included the "why no soft mask" comments. I tried changing the code in getNonStrokingPaint() like in getStrokingPaint() but the result was terrible, except for PDFJS-5853.pdf (the class photo in Israel) which was perfect for the first time.
There are some changes that I didn't use yet but will test later, against the "good results" that I have now.
