bool tuttle::plugin::quality::DiffPlugin::getRegionOfDefinition	(	const OFX::RegionOfDefinitionArguments &	args,
		OfxRectD &	rod
	)		`[virtual]`

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.
