-------------------------------------------------------------------

The last commits deal with what I mentioned a month ago re ghostscript bug 
691157. The commit never improved much, until now, and the results are amazing.

Improvements:
- bugzilla869140.pdf: I thought it was perfect, but there's more, e.g. an axial 
shading softmask in the girls room and a radial shading softmask in the dining 
room
- gs-bugzilla690351-p7.pdf: perfect, background structure
- gs-bugzilla690535.pdf: perfect, euro now in gold
- gs-bugzilla690839.pdf: perfect, shading
- gs-bugzilla691157.pdf: cutout (but some weirdness)
- gs-bugzilla691218.pdf: "sales event" in correct color
- gs-bugzilla691348.pdf: cutout
- gs-bugzilla692689-reduced.pdf: perfect
- gs-bugzilla692933.pdf: perfect, structure vanishes at right
- gs-bugzilla693520.pdf: perfect, including weird "box in water" effect
- gs-bugzilla693548-STACKOVERFLOW.pdf: perfect shading
- gs-bugzilla696682.pdf: perfect, arrows
- gs-bugzilla696864.pdf: dito
- *371: perfect, missing thing now there
- PDFBOX-3400.pdf: now correct shading
- PDFBOX-3400-RGB.pdf: now correct shading
- PDFJS-3096.pdf: probably perfect
- PDFJS-6113.pdf: color near websitetop left
- texample-rgb-triangle.pdf: shading fully visible but not correct colors

Changes:
- gs-bugzilla696026.pdf
- PDFJS-5811-2.pdf p2: hard to tell, shadows around region nantaise are a bit 
less

Regressions:
- *417_ weird triangle, some shadows gone?
- PDFBOX-2103.pdf: slight color difference at bottom of screen
