The 2a’s won by a large margin.
I committed the updates to zooming in the GUI. 1-click fast zooming zooms in and out using the display window and centering the map (i.e., region) at the click point. Zoom-in box zooming works as before. Zoom-out box zooming sets the zoom ratio with the longest box dimension, creates a new region that matches the box aspect ratio, and centers the new region in the display.
Thanks to all who voted and offered suggestions.
