- GSNPositionedEditPartBase*: Avoid code duplication by pushing refreshDecorationFigure() to PositionedEditPartBase
- PositionedEditPartBase.refreshDecorationFigure()
  - Avoid SWT Image leak by reusing the same icons
  - Add more null-checks to implementation
- MarkerViewPart -> column updater: Avoid SWT Image leak by disposing old image before setting a new one

- Keep order of elements to be selected (e.g., EENum values) etc. by using a LinkedHashMap instead of a TreeMap

Adds the possibility to filter the list of available choices for an enum-type annotation via the annotation's value provider.
Therefore, a map containing the class of the to be filtered model elements and the allowed enum literal must be given in the constructor of the value provider.

Bugfix: Use annotation instance key in setValue(). This is already done in getValue() / getLabel()

- Add Id, version, and ConQAT tags to XML files

* Mainly documentation cleanup
* Remove some commented out code

org.fortiss.tooling.kernel.internal.storage.eclipse.ModelContext:
org.fortiss.tooling.kernel.utils.EMFResourceUtils:
 - Resolve B.19 issue (numbering scheme as of Aug. 14, <https://af3-developer.fortiss.org/projects/autofocus3/wiki/Check-list_for_Code_Reviews/56>) "Use static imports"
refs 2255

- Annotations are now instantiated in ElementCompositorService. Hence, this migration will not be required in the future.
refs 2208

- Ensure that the annotation view is updated when switching between multiple projects by fixing a bug in the EAdapter registration
refs 2236

- Fix last commit: Actually allow one connection from a IHierarchicElement (node) to a free IConnector
refs 2233

- Prevent multiple fan-in for IHierarchicElement -> IConnector connections (was erroneously enabled in some cases)
- If this is desired, concrete compositors should override canConnectInterally()
refs 2233

- Instead, ensure that DiagramEditorBase has the focus when a child edit part is added or removed
- This works around #2207 and also the same part of #1491 as with the old workaround
- Summing up:
   - Undo/redo of operations on the model only works if either the NavigatorViewPart or a DiagramEditorBase has the focus
   - This makes sense if the active view provides editable items itself (e.g., the GenericAnnotationView) *and* provides undo/redo (currently not the case for GenericAnnotationView).
   - For other (read-only) view (e.g., Model Markers), this behavior is confusing for the user
refs 2207,1491

- Move annotation value service, annotation value provider base classes and annotation extension point to org.foritss.tooling.base
- Remove createEditingSupport() from IAnnotationValueProviderBase and move functionality to org.fortiss.tooling.base.ui.annotation.editingsupport.EditingSupportFactory instead
- Rename extension point to org.fortiss.tooling.base.annotation.

Example binding:

<extension point="org.fortiss.tooling.base.annotation">
  <annotation binding="org.fortiss.af3.timing.annotation.valueprovider.CIValueProvider">
     <modelElementClass modelElementClass="org.fortiss.af3.component.model.Component"/>
  </annotation>
</extension
- Adapt all known users of annotation framework to new structure
- The change is a preparation to fix #2208, i.e. to put the instantiation of a model element and its annotations into a single undo/redo command
refs 2208

- Avoid case distinction in GenericAnnotationView that handles construction of EditingSupport for boolean annotations
- This fixes the bug that the EditingSupport was only created correctly for derived annoations (#2225)
- Add TODO to delegate construction of label provider to annotation value provider, too (#2226)
refs 2225,2226

- Fix crash in some annotation value providers during undo/redo by checking if annotation specifications are registered with a model element
refs 2204

refs 2133

- If the annotations view is not visible (i.e., not opened at all, or not the active tab), create and raise the properties view
- Otherwise, just create the properties view, but do not raise it (the annotation view acts as a replacement for many properties)
refs 2133

- Change view ID to "org.fortiss.tooling.base.ui.annotationView" and define a Java String constant for it
refs 2133,1841

- Eliminate superfluous override of performRequest() because of the inheritance relation: ConnectorEditPartBase -> PositionedEditPartBase -> GraphicalEditPartBase
- GraphicalEditPartBase provides the desired functionality to raise the properties view, and PositionedEditPartBase does not override this behavior
refs 2133

- No functional change

- Install EAdapter for top level element of current project (instead of switching it the currently active root element (e.g., component architecture)).
- This ensures that annotation views are updated also on changes of models that currently do not have the focus (i.e. programmatic changes of models that are currently not shown in the diagram view)
refs 1841

- Display model element ID in tooltip (in addition to model element name). This is useful to identify selection targets for annotations of type EReference where the editor also displays the ID in order to distinguish elements with the same name.
refs 1841

- Add isAvailableObject() method that can be overridden by value providers in order to filter the set of available elements

LabelValueMapping: Use this filter
