# Maintainer: Daniel Bermond <dbermond@archlinux.org>

# NOTE 1:
# DPS (Display PostScript) feature is obsolete and thus not enabled.
# For more information about DPS being obsolete please visit:
# https://www.x.org/releases/X11R7.7/doc/xorg-docs/graphics/dps.html

# NOTE 2:
# Linking to ghostscript libs (gslib) is disabled due to security
# issues. ImageMagick will call 'gs' executable directly instead.
# See: https://bugs.archlinux.org/task/62171

# NOTE 3:
# change font directories in build() to match yours:
#   - deJaVu and GhostScript font directories are the default ones
#   - Windows font directory is set according to a Wiki example
