Issue DM-2849: Tweaks to OO display interface
When I wrote the initial version of display_firefly I found a few minor issues in the way I'd designed the Display class; at the same time, [~lauren] found some missing functions in the backward-compatibility support for ds9. Please fix these; note that this implies changes to afw, display_ds9, and display_firefly.
