Kenneth Moreland 6b1db2cf04 Check value type in Invoke input arrays.
Instead of just checking that a dispatcher's Invoke input is an
ArrayHandle, also check that the ValueType of the ArrayHandle is
compatible with the types of the worklet operator. This is done by
adding a template argument to the ControlSignature tags that is a type
list tag that gets passed to the type check.
