commit 6e45bb0bc682e20549ed2d9160cafaeaafbb8c24
Author: Deri James <[email protected]>

[gropdf]: Fix Savannah #65112 (subsetting).
* src/devices/gropdf/gropdf.pl (subs_call): Type 1 fonts have a section
of numbered subroutines which can be called from the actual glyph
definition; I have seen over 1000 in some large fonts. So, when you
are subsetting you need to subset (and renumber) any relevant
subroutines used by the glyph you are subsetting.
Fixes <https://savannah.gnu.org/bugs/?65112>.
