Hi Chambers and Alain,

I am also a programmer and when suggesting the new lasso feature, I had 
exactly in mind what Chambers explains.

But on the other side, I am not sure how and how much it affects the speed.

I would like to have here an opinion by someone from the POV-Ray team, as 
they know the source code the best, and can also very fine estimate how the 
new lasso would affect calculation amount and speed.

Greetings,

Sven
