ghostscript master 20171027

While mucking about with a broken postscript file, I notice from strace that
ghostscript is searching for files from the ghostpdl/Resource/ directory which
are not installed. This does not appear to cause a problem, per se, but it
also does seem very odd.

Even more odd, ghostscript is hardcoding a long Path variable which would NOT
find these files, even if the Resource directory itself *were* installed.

For instance, consider the file "ghostpdl/Resource/Decoding/StandardEncoding".

The hardcoded Path is:
/usr/share/ghostscript/9.23/Resource/Init:/usr/share/ghostscript/9.23/lib:/usr/share/ghostscript/9.23/Resource/Font:/usr/share/ghostscript/fonts:/usr/share/fonts/default/ghostscript:/usr/share/fonts/default/Type1:/usr/share/fonts/default/TrueType:/usr/lib/DPS/outline/base:/usr/openwin/lib/X11/fonts/Type1:/usr/openwin/lib/X11/fonts/TrueType:/usr/share/cups/fonts

And, strace sees:

"/usr/share/ghostscript/9.23/Resource/Init/Decoding/StandardEncoding",
O_RDONLY) = -1 ENOENT (No such file or directory)

A similar issue was reported a couple of years ago -
Bug 695873 - ghostscript can't find the Resource directory and the ICC profiles
director
- but there does not seem to have been any resolution from back then.

This seems like an issue that somebody should look into. I don't know that
there is any reason for the ghostscript process to be engaging in futile
"busywork", searching for many files which it will never find.
