* Initial attempt at getting the toolbar for the fixed position working with the Vue toolbar controls.
* Set title for controls
* Significant mods to support legacy Fixed Position
- Moved selection and editing styles into _global.scss;
- Changed class naming in legacy fixed.html to map to newer CSS styles;
* Pass in the color value
* Do not show the toolbar container if structure is empty.
* Use a plugin for fixed position to get access to openmct. Show the toolbar only if the object is being edited.
* Ensure fixedController is on the selection context when editing
* Add listener for a domain object with the same id only once.
Update the toolbar value after the object mutation.
Remove editor isEditing listener on destroyed.
* Remove space between the size and px.
If newObject exists, update the toolbar value.
* Remove --nwse class name which seems to be a typo
* use modifier convention
