The get RoD action.

If the effect wants change the rod from the default value (which is the union of RoD's of all input clips) it should set the rod argument and return true.

This is all in cannonical coordinates.

		OFX::Clip *&	identityClip,
		double &	identityTime
	)		`[virtual]`

client is identity function, returns the clip and time for the identity function

If the effect would do no processing for the given param set and render arguments, then this function should return true and set the identityClip pointer to point to the clip that is the identity and identityTime to be the time at which to access the clip for the identity operation.
