We should have them.

We made an explicit and carefully weighed special exception for colorimetry 
that it was OK for display plugins to ignore it.

But we never made a blanket rule that any other new properties could be 
ignored, at least not that I'd remember. Accordingly, orientation cannot be 
ignored - it is either supported directly in the display plugin, or handled by 
conversion/filtering.

However, in the specific case of stereoscopy, I suspect that any such filter 
will expose latent bugs with cropping and SAR again.
