Stretch / Compress Deformer update

Following on from my last post, I decided to take the compress deformer a bit further.

The idea is to create two input meshes that define the stretch and compress behavior for the source mesh, so when a face is being compressed, it will look up the components of the compress mesh and use that to define where (approximately) it's points should go. Same goes for the stretch.

I ran into an annoying bug with the MFnMesh.getNormals() function. After getting weird results with the deformation, and re-checking the code several times, I decided to turn to google and see if anyone else had the same issue. Lo and behold, apparently .getNormals() returns some normals in the wrong order. One to keep in mind.

 If you haven't already seen this awesome plug-in, it does this sort of thing, only much better. Seriously cool stuff. Check it out. :)
