I want display axes to swap automatically for images, as they already do for MSs, when the user changes just one axis (using the Options panel 'Display axes' section). This will avoid the user's needing to make two changes, and having nothing work or display in between.
(This is an internal library, not strictly a Qt-layer change. But it's motivated by removal of 'auto-apply' in the Qt interface layer (everything 'auto-applies' now)).
