Log Message:
The code which calculates linear gradients divides by zero under some
circumstances. This leads to NaNs passed to cairo which makes that
literally "nan" is inserted into the output file when printing. The
resulting file crashes ghostscript, and also poppler when it is fed
to it again.
I didn't read PDF specs yet to understand where the math is failing,
just avoided the division by zero.
