Multi-Zone Grid: Define Shape - Add Zoom

I’m making some updates to a module that I recently started playing and discovered a handful of minor errors.

One of those errors is that some of the Zone Definitions are wrong. In trying to fix this, I’m looking at every Zone Shape and fixing as needed.

The lack of zoom is adding significantly to the time required to do this. I want to be able to zoom out to see if the overall shape is right, locate any vertex errors, then zoom in to the trouble spots. Instead I have to manually scroll the entire shape and repeat for all ~40 areas on the map.

Zooming in also allows for more precise location of vertices (which is helpful for complex shapes).
