Fixed bug with un-normalised ellipse area lights not having proper area calculation and erroneously reverting to quad lights.

Not too sure if it might be "the time" to integrate this over the approximate in another PR for 4.0 (if at all). I will do a test of this soon.

I am working on changing point light to sphere…

Adjusting spotlight blend using gizmo does not register undo

There is a pull request for that which has not been properly reviewed #104888, because there were a few mixed changes and the expected behaviour is unclear.

Cycles: Light leaks through objects in certain situations.

This happens because some light samples lie exactly on one of the triangle edges, due to numerical issues when sampling spherical triangles. But I'm not sure what's the best solution here.
