Fetch the ramp from an OP node's ramp parm. May return false if the OP or parm is not found, if the parm is not a ramp, or if the UT_RampOpResolver is not assigned by setRampOpResolver(). is_rgb, op_id, and op_version are optional return values for the type of ramp, the parent node's unique ID, and the parent node's version parm serial (as reported by getVersionParms()).
