How can I override the default mouse left click behavior that pans the plot and implement a zoom to the area selected by the mouse. More specifically, I would like to implement the following:
- Left click to define zoom start
- Drag to define a rectangular zoom area. A filled rectange should be rendered on the screen while the zoom area is being defined.
- Click release to define zoom end. The plot now zooms to the defined area.

What you are describing is currently available as "1 button" mouse mode,
and is available via the left-click context menu under "Mouse Mode".
