# 20191231 bkw:
# - take over maintenance
# - update for v3.28.5.3, which is the last version that will build with
#   Slack 14.2's rather outdated gtk+3 libraries. Actually it requires
#   some fugly hackery to work, see shim.h for gory details and polemic.

# 20200101 bkw: "shim" to let us actually compile with gtk+-3.18 and
# glib-2.46.2. Supposedly these versions are supported by evince-3.28.5,
# but upstream uses a couple of functions that are new in gtk+-3.22
# and glib-2.52. Fortunately it's stuff we can work around with a few
# #defines.
