PlanarI is a mix-in class to be implemented by Iops which prefer to be accessed in a planar way (i.e. with fetchPlane)
It is not itself an Iop because the subclasses might want to inherit from some other subclass of Iop.

whether the Iop prefers to output packed or unpacked data. If the Iop is neutral it should return ePackedPreferenceNone and then the decision will be made on whether other criteria, such as what the downstream ops prefer to consume

override this if you want your planes to be different to the default.
by default Nuke will call renderStripe()/doFetchPlane() once for each layer. You define its belief about what a 'layer' is here. for example, if you return info().channels(), it will render all your channels at once; if you return chan it will render each channel seperately.
Reimplemented in DD::Image::Read.
