// Careful here... We might detect that one of our subcontrollers
// has animation keys that all have the same value. That doesn't
// mean they're all zero though. An avatar animation might have
// elbow bend a constant 90 degrees through the entire anim, but
// if we delete the controller and assume zero, we'll have problems.
// Transform controller channels get around this by sampling the source
// first and using that to fill in the missing subcontrollers.
//
// Note: that one of our subcontrollers could itself be a compound
// controller. An example would be a controller for XYZ Euler angles
// that's a sub of the pos/rot/scale transform controller.
// It's possible that some of these sub-sub controllers could be
// removed, but then we'd have to store the default values somewhere.
// At the moment, this doesn't seem likely to save us enough space
// to be worth the effort. (This is why this function doesn't
// recursively call purge on its subcontrollers.)
