[away3d] Flip BitmapMaterial in back for Plane Object

[tsangwai...@gmail.com]

Hi,

I am wokring on a plane object and have material on back. But i find
that the back material is flipped.

I dig in the group. I get a solution for MovieMaterial( scaleX to -1).
But i can't find a solution for BitmapMaterial.


Solutions i have now
1. Use 2 plane
2. Use a Cube Object with depth = 0
3. Flip the bitmapdata

But seem all 3 generate overhead compare to just using 1 plane.
