Creating a placeholder Jira for the following scenario: it would good to have inline (read: on canvas) controls for zooming diagrams like Stunner, DMN, GDT, and Case Modeler.

This would move the controls off the toolbar and thus could happen after or instead of that part of JBPM-7433 and DROOLS-2734.

Accounting for inline zoom will allow the Manage section to display process diagrams that can be zoomed without adding an unnecessary toolbar.
