Very slow rendering of file with pattern reuse
gs-bugzilla692158-schleuse-veryslow.pdf
file is from ghostscript: https://bugs.ghostscript.com/show_bug.cgi?id=692158
I am using version 0.88.0 of cygwin.
The rendering has been running for at least an hour. There are 20 patterns, but these are reused a lot.
