What is GI, AO ?

About soft shadow... if it's a point of light, it cannot be soft.-

Or you have a definition of point that is no more a point.

Area lights have many optimisation (such as adaptative) which can be
used to have real large array without the cost of as many point lights.

jitter, orient & circular are cool too.

Maybe wanting something like the fading cone of spot light ?
