Active the hand when we have leap hand data.
Apply Leap data directly to skeleton.
Check palms' active state, apply rotations.
Derp; I don't want the length of the scale, I want the average of the
components.
Swap the palms if they're in the wrong order.
Gravity adjustments.
Working on wiring up the fingers.
Removed unused variable, debugging code.
Adjustments to wrist rotations.
More palm fixes.
Attempting the fingers again.
