Local zoom values for each template individually

[magoorden]

Is your feature request related to a problem? Please describe.
Currently, the zoom setting is applied equally to all templates in a model. In editor mode, this can be annoying when one switches (often) between templates.

Take for example the SchedulingFramework example. When you Zoom to Fit the Task template, one gets a nice overview of that template, but then switching to Policy_FPS makes that template small. Now, when you Zoom to Fit this Policy_FPS, the Task templates also gets zoomed in and becomes unreadable.

Describe the solution you'd like
The zoom action (Zoom to Fit, Zoom In, and Zoom Out) should only apply to the current active template in the editor mode.

Describe alternatives you've considered
When switching templates, one can consistently click Zoom to Fit.
