[Bf-cycles] Why remove square samples?

Hello List,

one question regarding squared samples: It seems to me that squaring the 
samples is a convention among pathtracing engines. At least Arnold is 
also using squared samples.

Does anybody here have experience with other engines like octane? Do 
they square the samples as well?

The reason for squaring: To get half the noise you need to quadruple the 
samples (because a pixel has two dimensions).
