# enough so detail isn't destroyed.

# Currently only processes the chroma, as that's what sharpeners that cause the
# ringing in the first place operate on.
#
# depth ........ Depth of the AWarpSharpening
#
# diffthresh ... differences between the source and the sharpened clip larger
# than this will not be touched; the smaller the difference the
# more of the sharpened clip will be used
#
# lumathresh ... since the ringing is mostly notable in bright places this
# threshold will prevent dark areas from being hit too hard, so
# for instance linework will be preserved

# debug ........ 0 - normal operation
