[curve 2] is quite slow for drawing a single line,
I use an abstraction made with the openGL objects (see attachment) that 
is compatible with [curve 2], but lot's faster when you have 1000 lines 
to draw...

I don't understand : [curve 5] get inputs for 5 differents points. you 
can do segmented line abstraction using openGL wrapper (as in [curve2]).
what do you want more?

the first time i saw this was in Iohannes (or someone else) examples patch.
IMO, this kind of example are really missing in the gem official
