# Notes:

# PDFACompatibilityPolicy=3 actually doesn't exist. A bug in ghostscript
# interprets is as something between 1 and 2, without unnecessary failing on

# Add -dNoOutputFonts if you absolutely totally need to get rid of fonts in a
# figure PDF. Do not do that for the whole thesis though-- a thesis with
# removed font glyphs is not submittable!
