# This one's tricky. ink/stitch doesn't actually _use_ gi.repository.Gtk,
# but it does use GTK (through wxPython). pyinstaller has some special
# logic to handle GTK apps that is engaged when you import
# gi.repository.Gtk that pulls in things like themes, icons, etc. Without
# that, the Params dialog is unthemed and barely usable. This hidden
# import option is actually the only reason we had to install python-gi
# above!

# the duplication. This significantly decreases the size of the inkstitch
