Description
Anim layer blending currently supports two modes, overwrite and additive. However the additive mode currently works by blending each layer together in a linear combination using their weights. This is much akin to the direct blend mode of blend tree's. The engine should also support a mode which adds the difference of each layer onto a bone subsequently using a reference pose to create the additive difference.

Research direction
Start by locating the animation-layer blending implementation and its existing overwrite and additive modes. Compare the requested reference-pose difference behavior with the current weighted additive blending. Done means the engine supports a mode that adds each layer's difference from a reference pose onto the affected bone.
