Subject: [PATCH] Redirect gs stdout to stderr. This will prevent warnings to
be part of the generated file causing broken files. This does not redirect
drivers output which still write to stdout.
I'm currently seeing "**** Warning: glyf overlaps cmap, truncating."
during esptopng conversion leading to broken .pnm.
This change prevents the broken .pnm file.
