Smooth normals weighted by face area

Smooth shading mode which weights face normals based on face area, giving larger faces more influence.  This would significantly reduce the need to add extra supporting geometry in order to get flat faces, which is especially important for game assets where every vertex counts. [Also see this answer on B.SE ]( blender.stackexchange.com/a/70347/599 ). ---- In case you are wondering, the example in the gif was created by manually editing the normals with the blend4web addon.
