[away3d] refreshPatch does not work in 3.6

[Sylvain Godbert]

Hi,

I have an animation that uses refreshPatch to force Away3D to redraw a
BezierPatch object. Problem is that refreshPatch has no effect in 3.6
while it worked with 3.5.

Is this a bug or shall I use a new function for that ?

Cheers

Sylvain
