+Subject: [PATCH] pdfwrite - more improvements for mesh shadings
+
+Bug #707655 "No output visible with pdfwriter"
+
+commit 3d6e3acbcda79a0096cd1ad73c7b9b1101a43187 to fix bug #06852
+unfortunately led to this regression. The problem is related to the
+scaling of co-ordinates performed when a mesh shading has vertex
+co-ordinates which are too large for Acrobat 5 (PDF 1.4).
+
+Acrobat 5 has a limit of =/-32767 on real numbers, which applies to the
+/Decode array of a mesh shading. Because this is an Acrobat limit, not a
+limit of the PDF specification we would ordinarily ignore it, but the
+PDF/A-1 specification chose to carry the Acrobat limitations into the
+PDF/A spec.
+
+This commit fixes the problem by correctly scaling the co-ordinate
+values to the Decode array values when outputting to PDF 1.4 or less,
+even if no actual co-ordinte scaling is required, and modifying the
+/Matrix of the Pattern to scale up the Decode values to the real
+co-ordinates. Crucially we must not scale the Tx and Ty values of the
+CTM.

+Description: Allow the build timestamp to be externally set
+ In order to make Ghostscript output reproducible, we need a way to
+ set the build timestamp to other values than the current time.
+ We now consistently use gp_get_realtime() instead of directly calling
+ time() or gp_get_usertime() and make gp_get_realtime() use the value
+ found in the SOURCE_DATE_EPOCH environment variable if set. Also,
+ environment timezone is fixed to UTC if SOURCE_DATE_EPOCH is used to
+ avoid variations.
