Graphic Objects & Memory Use

[Gordon Webster]

Dear Revolutionaries

I have a question or two about rev's graphic objects
...

Since the rev graphic objects such as lines and shapes
are objects that can have their own properties, styles
etc., is there a big memory overhead in using them to
create complicated graphics? 

What would be the best way in rev to do the equivalent
of double-buffering the graphics i.e. invisibly
drawing the next frame of a complex graphic in
background and then displaying it?

Happy New Year to you and yours.

Gordon
