[Suggestion] Ability to invert normals on a voxel, so you can make outlines

Basically, the idea is that by covering a model in voxels that have inverted normals, you create an outline around the model. The intent is that this makes recreating outlined 2D pixel art easier.

Im really not sure what you are asking. Can you explain a little more?

This post I made a while ago on the Minecraft forums demonstrates basically the same idea: http://www.minecraftforum.net/forums/mapping-and-modding/resource-packs/resource-pack-discussion/1256364-texture-artists-union?comment=49016
And this gif show a similar effect: http://cezkid.deviantart.com/art/pixel-3D-Megaman-168294112

Mhmm, interesting idea for an outline. I don't think it's hard to implement, but would have significant rendering performance impact. Why not use a shader instead?

Because I'd like to have finer control over the look of the outline than what a shader can offer. How much of a performance impact would it actually have? And I would assume it would only have a performance impact when inverted voxels are actually in the model, right? I wouldn't want to hinder others who don't want to use outlines.
