Idea: Highlighting new parts in a step

[Gerald Lasser]

I did use the GUI of LDView to get the pictures and merged them in GIMP.

What I can find in the LDView manual are the following command line parameters for the "edge-highlight" render:

EdgeThickness (Integer, 1-5) -> 5
EdgesOnly (Boolean) -> YES
SaveAlpha (Boolean) -> YES

The rest, camera position, image size, anti-aliasing etc. can stay the same.
