[Papervision3D] adding copyTransform to Matrix3D and getting back a pure array

[Carlos Ulloa]

Hello John,

Feel free to include it, but I maybe would call it toArray().

In DisplayObject3D there's already a already a new method

copyTransform( reference:* )

It copies the transfom Matrix3D of an DisplayObject3D instance (or just a
Matrix3D object, hence the *) to another instance.

So, after very recent debugging, this is finally working

camera.copyTransform( xWing );

It should effectively create a first person view from any object. Got to put
a few more planes on the floor and try it on the focus actually. :-)

We could also add a DisplayObject3D method we could call getTransformAsArray
that would do it for you directly. There's already a couple
getOperationAsString in AS3, not idea what they do, but I think it sounds
similar.

This functions have zero impact on performance, very low impact on footprint
or file size and can be very useful for other people.

I believe what we want is not just a 3D engine, but the most complete
interactive 3D framework we can build.

Microsoft XNA Game Studio is a good example of what we should dream with.

Go ahead and commit,
