Make CompositeArray work if functions to get data return None
astrofrog
committed
Add enable() method for layer artists

Update image viewer so that we check whether an image layer is compatible with the reference data before plotting

committed
Fix tests

Update compatibility if layer changes (not just reference data)
astrofrog
committed
Simplify implementation of DataRemoveComponentMessage
