# NOTES:
#
# * cups is dlopened.
#
# * libpng is also dlopened but only by libsplashscreen, which isn't
#   important, so we can exclude that.
#
# * We still need to work out the exact AWT and JavaFX dependencies
#   under MacOS. It doesn't appear to use many, if any, of the
#   dependencies below.
