LC-Magick #12

[hh]

Added today #12: Before-After-Image

Before-After-Image shows horizontally or vertically an "original" image
(image "before") and a part of it visually replaced by the changed image
(image "after"). 

You select the proportions of the parts by sliders.
The stack is "pure" LC Script and runs with LC 6/7/8/9 on Mac/Win/linux.
