# iip : Integrated Image Processor, v.0.5a
#
#
# ---------------
# | It is slow. |
# ---------------
#
# New in v.0.5 :
#
# EQ [int] : Edge quality. 0=deaktivated (don't do that!!!), 1=standard (as formerly), 2=better'n'slower, 3=evenbetter'n'evenslower
# Note: when using EQ = 2|3, then it's a good idea to *DEACTIVATE* deringing in iiP (don't hit the dog twice).
#
# warp_Y, warp_UV [bool] additional Luma & Chroma Warping.
#
# Luma warping should make the picture more 'gracile' when upsizing to bigger resolution, e.g. DVD -> HDTV.
# For same resolution or downsizing, it may (?) help for sources with distorted detail. Or it may not - YMMV.
#
# Chroma warping helps on sources with bleeding colors (e.g. Enterprise: on the uniforms, the red stripes are bleeding into
# the blue cloth, which looks *very* ugly [like an aquarell that's gotten wet]. It looks much better with chroma warping.)
# On clean sources, chroma warping is a waste of CPU cycles.
#
# exborder [bool] : exclude outmost 8-pixel-border from sharpening (gradient masked)
#
# dering: old method: called with positive values for "dering"
# new method: called with negative values for "dering" (better, but slower)
#
# detail_floor [int] : was formerly hardcoded, now user-definable. default 20.
#
