vcl: make "Reduce Transparency" parameter tweakable
"Reduce transparency" feature previously was using hardcoded
value of 0.25. If current object area to whole printing area
ratio exceeds this value, object is being written without
any extra transparency layers in order to reduce metafile size.
Right now this value can be adjusted in "Expert Configuration".
Parameter is called "ReduceTransparencyMinArea".
