Changes

[NONE] Ensure DOT tests bundle does not export package.

Fixed org.eclipse.gef4.dot.tests exported
org.eclipse.gef4.dot.internal.parser package, which is only internally
used.

[441352] Add support for polygon-based node shapes

- Add rendering support for "ellipse", "invtriangle" and "triangle" node
shapes.

[441352] Increase DOT version to 1.0.1 to reflect latest changes.

Increased version of DOT.UI and related doc, tests, and sdk bundles to
1.0.1. to properly reflect the latest changes.

[NONE] Add test for FXControlAdapter.

[497224] Ensure IDomain.execute() accepts progress monitor.

- Added IDomain.execute(ITransactionalOperation, IProgressMonitor) to
complement IDomain.execute(ITransactionalOperation).
- Moved implementation of
AbstractDomain.execute(ITransactionalOperation) over to new execute
method, and have it delegate to new method instead, passing over a
NullProgressMonitor.
- Deprecated execute(ITransactionalOperation), which should no longer be
used.
- Increased version of MVC and related doc, tests, example, and sdk
bundles and features to 1.1.0.

[NONE] Update feature dependencies and version in category and pom.

- Update category.xml to refer to increased feature versions.
- Ensure feature dependencies are now based on compatibility, not
equivalence.

[NONE] Leave package exported but add api filter.

- As the package-export for the org.eclipse.gef4.dot.internal.parser
package is re-generated by the GenerateDot.mwe2 workflow, leaving the
package-export in place, but adding an api problem filter. Disabling API
tools is not desired, as the tests bundle BREE compliance can no longer
be checked.

[NONE] Create README.md file.

Created README.md file with general project description

[497495] Optimize performance of AbstractInterpolator.

 - Arranging the decorations does only apply one transformation change,
   instead of three.

[497848] Guard refreshVisual during EdgePart#bendContent().

[497679] Ensure UI is updated while processing events.

[497584] Ensure GeometryNode aligns clickable area and geometric shape.

[497555] Ensure transformations can be changed at once.

 - Provide "affine" property that can be set by the user.

[NONE] Increase version numbers.

[496227] Fix memory leak resulting from not disposed parts.

- Ensured that AbstractBehavior disposes all handle and feedback parts
it removes.
- Ensured that ContentBehavior disposes the contents parts within its
pool when being disposed.

[NONE] Implement additional dot validator test cases.

- Add test case for validation of a non-directed edge within a directed
graph.
- Add test case for validation of a directed edge within a non-directed
graph.

[NONE] Fix versions after reverting commit.

[NONE] Increase versions in the category.xml.

[496423] Ensure rotate cursor image is properly deployed.

- Create images source folder and add rotate_obj.gif to it.
- Added images source folder to build.properties.

[497062] Ensure decoration style is applied to decorations.

- Ensure decoration style is applied to decorations even if the
decorations are not set via Zest properties, but directly on the
connection.

[495455] Update tycho.scmUrl to GitHub repository location.

[498035] Allow null argument in ContentPolicy's setAdaptable() method.

- Avoid IllegalStateException when disposing: in this case the
setAdaptable() method will be called with a null argument.
- Modify the IAdaptable documentation within the gef4.common and
increase its version number from 1.0.0 to 1.0.1 to reflect the changes.

[NONE] Ensure test data is queried from UI thread.

[498045] Centralized disposal of ContentPartPool.

- Ensured the shared single ContentPartPool instance is disposed by
AbstractViewer and not ContentBehavior.
- Made ContentModel, FocusModel, HoverModel, and SelectionModel
disposable, so all visual parts are properly removed when the viewer is
disposed.
- Ensured viewer disposes all its fields and detects whether the content
part and visual part maps are not properly cleared.
- Fix AbstractLogoHoverHandlePart did not properly unregister.

[498045] Add missing @since tags.

[497679] Ensure all events are correctly dispatched.

Deferring of events is not working as intended, because some events are not
processed when they are deferred. Therefore, I ensured that a UI update is
performed ca. every 40ms while all events are dispatched normally.

[498061] Add JUnit test for the intersection point calculation problem.

[497076] Add snippet to demonstrate opacity issue.

[498061] Improve performance of BezierCurve#getIntersections() for some non-intersections.

[NONE] Print emitted mouse events in failing tests.

[495455] Add initial travis build configuration.

- Add a .travis.yml build configuration file that uses Neon.target.
- Ensure maven.test.failure.ignore can be overwritten via command line.
- Ensure travis build configuration passes maven.test.failure.ignore=false as an option.

[NONE] Update versions from 1.0.0 to 1.0.1.

[498158] Add support for maven.javadoc.skip and wikidoc.skip.

- Ensured that javadoc generation respects the maven.javadoc.skip option.
- Added a wikidoc.skip option that is respected by the wikitext generation.
- Ensured travis configuration skips wikidoc generation (while it still generates javadoc, as this might affect the build result).

[498158] Fix wikidoc.skip option was not correctly passed.

[477980] Add support for rendering multiple arrow shapes.

- Change the return type of the private computeZestDecoration method of
the Dot2ZestAttributesConverter class from javafx.scene.shape.Shape to
javafx.scene.Node.
- Change the return type of the public get/getDefault method of the
DotArrowShapeDecorations class from javafx.scene.shape.Shape to
javafx.scene.Node.
- Extend the implementation of the public get method of the
DotArrowShapeDecorations class to handle the multiple arrow shapes
properly (and not only their first arrow shapes).
- Extend the DotBsplineInterpolator to arrange the decorations properly:
ask each PrimitiveShape for its individual offset to consider.

[477980] Rename interface "PrimitiveShape" to "IPrimitiveShape".

[498199] Fix FXCanvas was not properly disposed.

- Replaced FXCanvasEx.dipose() (which is still preserved because of API
compatiblity reasons) with dispose listener.
- Ensured scene is unset when being disposed, to cursorChangeListener
and event dispatcher are properly unregistered.
- Changed implementation of RedrawingEventDispatcher to better
encapsulate that it wraps the 'original' event dispatcher. Ensured that
it is properly disposed as well.
- Ensured SWT2FXEventConverter clears all its fields when being
disposed.

[498251] Ensure PropertySheetPages are properly disposed.

- Fixed that AbstractFXView and AbstractFXEditor did not dispose the
PropertySheetPages that might have been created through getAdapter().
- Ensured all local fields are cleared after having been disposed.

[498191] Ensure AbstractDomain is properly disposed.

- Ensured operation history listener (for transaction changes) is
properly unregistered when domain is diposed.
- Transferred uncaught exception handler into a constant, so it can be
shared by several domains (and does not have to be unregistered when
disposing one of them).

[NONE] Stabilize UI tests.

 - All UI related code is executed on the UI thread.
 - Console logging is activated.

[NONE] Rename 'id' parameter of DotAttributes._setName() to 'name'.

[498251] Remove unnecessary disposal of UndoablePropertySheet.

- Removed superfluous disposal of PropertySheetPage from AbstractFXView
and AbstractFXEditor.

[NONE] Deprecated the protected infiniteCanvas field in FXViewer.

[498277] Ensure FXViewer unregisters its listeners in dispose().

[NONE] Ensure viewer contents is cleared when Logo View is diposed.

[491261] Merge DotInterpreter into DotImport.

- Embed the DotInterpreter java class into the DotImport xtend class.
Use the xtend create function and lambda expressions to make the
implementation of the dot import logic more concise.
- Embed the test cases defined within the DotInterpreterTests class into
the DotImportTests class (eliminate 6 redundant test cases, improve
other DotImport test cases).
- Delete the DotInterpreter.java and the DotInterpreterTests.java files.

[498150] Ensure UI tests are stable on CI build infrastructure.

- Replace MOUSE_ENTERED wth MOUSE_ENTERED_TARGET, so all events can be processed via the scene.
- Moved all Robot calls into EventQueue.invokeLater()
- Ensured FXTypeToolTests request focus rather than moving mouse cursor.

[NONE] DotUI - Use ProjectionStrategy() instead of ChopBoxStrategy().

- Improve Dot Anchor rendering.

[498298] Ensure BehaviorUtils detaches anchoreds before removing them from the root.

Detaching the anchoreds from their anchorages ensures that the content part
anchorages lose their link to the viewer, and therefore, are unregistered from
the content-part-map.

Revert "[491261] Merge DotInterpreter into DotImport."

This reverts commit 8c2b3676a4f3cf8cee631edb93e17c8f1781de38.

Reverted because xtend generated code does not match the BREE version.

[498150] Set waitForIdle on Robot per default.

- Set wait for idle option on robot.
- Ensure event synchronizer uses JavaFX event thread, while all robot
calls use AWT event dispatching thread.

[498150] Ensure Robot is not called from AWT event dispatching thread.

- Ensured Robot is not called from event dispatching thread.
- Ensured position computation for move is performed in JavaFX
application thread.
- Placed panel in screen center.

[NONE] Use the correct import statement for the Connection class.

- Use org.eclipse.gef4.fx.nodes.Connection instead of
java.sql.Connection for importing the right Connection class into the
ZestProperties class.

[NONE] Improve javadoc of the DotAttributes class.

[498150] Call robot synchronized, ensure synchronizer waits for idle.

- Moved JavaFX initialization into static initFX method.
- Made robot functions synchronized.
- Ensure synchronizer waits for JavaFX thread to be idle.

[NONE] Fix typos within the Cloudio component
