It looks like this.

This is what I expected and was suprised not to get.
I can live without shadowless spotlight, but if existed it would be useful
in some cases. For example: now I have a scene with the building which is
illuminated inside. I want to use as few lights as possible (34 actually)
so "shadowless" allows me to reduce the number of them. But if they become
point lights I will lose control on what is illuminated.
