---+ regressions introduced by Fill+stroke commit

https://ghostscript.com/~regression/release__gs/compare1242.html#21691 - FIXED

   * %GREEN%Third image down, the dark blue stroke bounding the mid blue underline has significantly reduced thickness. Seems to work correctly with clist, badly without.
   * %GREEN%-sOutputFile='tests_private__pdf__sumatra__893_-_details_missing_in_tape_reel.pdf.ppmraw' -dMaxBitmap=400000000 -sDEVICE=ppmraw -r300 -Z: -sDEFAULTPAPERSIZE=letter -dNOPAUSE -dBATCH -K2000000 -dClusterJob -dJOBSERVER ../tests_private/pdf/sumatra/893_-_details_missing_in_tape_reel.pdf
   * %GREEN%Fixed with https://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=76fb18bc255a88cab5fbb2410b411e580f53486d

https://ghostscript.com/~regression/release__gs/compare807.html#16450 - FIXED

   * %GREEN%Black frame surrounding light gray background of the text box, again the stroke is noticebaly too narrow. Again seems to work correctly with clist, but not without.
   * %GREEN%correct: gswin64c -dMaxBitmap=400000000 -sDEVICE=ppmraw -r300 -dNOPAUSE -dBATCH -sOutputFile=out%d.ppm
   * %GREEN%incorrect: gswin64c -sDEVICE=ppmraw -r300 -dNOPAUSE -dBATCH -sOutputFile=out%d.ppm
   * %GREEN%Fixed with https://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=76fb18bc255a88cab5fbb2410b411e580f53486d

https://ghostscript.com/~regression/release__gs/compare320.html#5538 - FIXED

   * %GREEN%The PDF file produced by the pdfwrite device renders correctly in Acrobat, and when using the clist, but when not using the clist there's a missing orange stroke surrounding the sunburst which brackets the 'TE' in 'ORTEGA'. Robin opened a bug for this one here https://bugs.ghostscript.com/show_bug.cgi?id=702131 with a simplified file.
   * %GREEN%gswin64c -sDEVICE=pdfwrite -o out.pdf Bug693220.pdf
   * %GREEN%incorrect rendering gswin64c -dMaxBitmap=400000000 -sDEVICE=ppmraw -r300 -dNOPAUSE -dBATCH -sOutputFile=out.ppm out.pdf
   * %GREEN%correct rendering gswin64c -sDEVICE=ppmraw -r300 -dNOPAUSE -dBATCH -sOutputFile=out.ppm out.pdf

https://ghostscript.com/~regression/release__gs/compare674.html#13228
   * The PDF file produced by the pdfwrite device renders differently with Ghostscript and is (subtly) different when exported to TIFF from Acrobat. There appears to be a bug for this one already: https://bugs.ghostscript.com/show_bug.cgi?id=702033 However there's no progress in 6 weeks. In addition I see differences when rendering the PDF file in Acrobat and with earlier versions of Ghostscript.
   * %GREEN%Fixed in : <a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=f51ae6f4bf85dfa5be4b48a1a46ac69c653500c3" target="_blank"><font color="#002210" face='"Bitstream Vera Sans Mono","Andale Mono",Courier,monospace'>http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=f51ae6f4bf85dfa5be4b48a1a46ac69c653500c3</font></a>

https://ghostscript.com/~regression/release__gs/compare691.html#13696
   * The PDF file produced by the pdfwrite device after the filll+stroke commit renders the blue lines considerably darker than the PDF file produced before that commit. Acrobat displays both PDF files apparently identically.
   * %GREEN%Fixed in : <a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=f51ae6f4bf85dfa5be4b48a1a46ac69c653500c3" target="_blank"><font color="#002210" face='"Bitstream Vera Sans Mono","Andale Mono",Courier,monospace'>http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=f51ae6f4bf85dfa5be4b48a1a46ac69c653500c3</font></a>%ENDCOLOR%

   * %GREEN%The psdcmyk16 device has the image of the Earth missing. Other devices appear to be unaffected.
   * %GREEN%gswin64c -sDEVICE=psdcmyk16 -o out.psd Bug695916.pdf

   * %GREEN%Gray gradients turn blue with the psdrgb device since the fill+stroke commit. There are many examples, this is a reasonably simple example

%GREEN%We additionally have the bug reported by Serendipity (probably the only customer even aware there is a Release Candidate, let alone tested it) https://bugs.ghostscript.com/show_bug.cgi?id=702128 - FIXED with https://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=646007af056447fefd61eabfcdae85bfd6017d24

---+ Overprint regressions

https://ghostscript.com/~regression/release__gs/compare1306.html#23085

   * Looking at this I see that there is a bug, but it appears (to me) to be a long-standing bug in pdfwrite, which is not tracking overprint mode properly. I have a tentative fix, but this is not a regression so I don't think we should hold anything up for this.

https://ghostscript.com/~regression/release__gs/compare1306.html#23086 - %GREEN%FIXED

https://ghostscript.com/~regression/release__gs/compare1307.html#23090 - %GREEN%FIXED

%GREEN%In all three cases there are crosses (intended to indicate whether overprint is correctly processed) which appear or disappear. It seems likely the disappearing crosses are in fact progressions, but the ones which appear are probably regressions and I cannot make the red cross on a white background appear in Acrobat no matter what combination of profiles and overprint simulation I use, this appears to be quite incorrect.

%GREEN%Chris points to this commit http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=b7d32c453538bee41c34f8a77a3feb1dcc0ce759 and notes that we accepted problems at the time because there were more progressions than regressions. This was commit http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=b7d32c453538bee41c34f8a77a3feb1dcc0ce759
