Yes, that's what I meant.

Great! That would be a Wonderful option to see implemented!

It makes lots of sense to me.

But to see the single buffer mode to disapear from Gem,
does that mean we will have to render all the geos we want to
display at each frame? I think in the case when accumulating
a large number of geos. buffer 1 is very usefull in this kind of situation.

Many thanks.
