From Michael Platings,

- Animations with equal priority are now weighted correctly relative to each other
- (minor) Channels no longer store their weight as the only time it's used is in update() when Animation can pass in the weight directly
From Cedric Pinson,
- I adjusted the quaternion blending to keep the commutativy property
