Problem mit linedarken_toon

# LineDarkenToon use the idea of mf_toon (0.5) for linedarken.
# I wanted a really small fast code like FastLineDarken but with similar output like
# mf_toon and this is the result.
#
# needed filters:
#	- WarpSharp
#	- MaskTools v2
#	- AWarpSharp
#
# Common parameters are sstrength, sdboost and srange. 
# If speed is most important for you, test fast=true.
# With fast=true no edgemask will be created, just a simple fast weighting.
# But this looks imho still better than FastLineDarken.
