You can also turn on options -# using PNG_<option>_SUPPORTED.

Be -# very careful to change only settings that don't alter the API -# because this approach bypasses the private build checking. You -# can also change settings from pngpriv.h (read pngpriv.h) safely -# without API changes. Do that in the same way. -# -# 3) Write a new '.dfa' file (say 'pngusr.dfa') and in this file -# provide override values for setting entries and turn option or -# chunk values explicitly 'on' or 'off': -# -# setting FOO default VALUE -# option BAR [on|off] -# -# Then add this file to the options.awk command line (the *first* -# one) after this file.
