Description Mark van Rossum 2015-05-28 09:58:25 UTC 
I'm using either okular or evince to render the following PDF:

http://www.physio.unibe.ch/~senn/group/publications/ftp/paper_Synalgo.pdf

Figures 3,4,5,6 (pages 9, 10 and 11) are incorrectly rendered.

Big black boxes show up surrounded the figures.

GV and acroread display the file correctly.

bit more info:

I tried pdftoppm with both poppler 0.30 and poppler-0.33.0 (compiled from source).
Both gave same problem.

Initialize gamut mapping multipliers in ::copy() functions

This patch fixes it:

The gamut mapping multipliers were not copied in GfxCalGrayColorSpace::copy() (and in GfxCalRGBColorSpace::copy(), too), which causes here the usage of uninitialized memory.
