[GEM-dev] curve3d acts very very odd with lots of control points OSX+Linux)

[cyrille henry]

hello,

your patch works for me.
i've got a problem with more than 30x24 control points : changing 
control point does have no effect. it's the only problem i've got.

anyway : curve3d is very slow, creating a 32x24 control point will use 
all CPU of a standart computer.

i've got a standart gem version.

hum, strange.
