Summary:
This is a constraint that measures the distance of a joint from the provided
origin and penalizes if that distance is not equal to the desired target
distance. This can be used to enforce e.g. distance-from-camera constraints.

Summary: Should be mean/std not min/max.

Differential Revision: D69750023
Summary: We need this to support camera projections in pymomentum.  We'll allow a separate projection matrix per-constraint to support generating a linearized projection for each pixel constraint.

Differential Revision: D69750025
Summary: We need to be able to compute the change in gradient wrt the projection to support differentiable IK.
