* Network: preload images in options for all shape types
Fixes#3532
If the images option is set, preload it, even if the node shape is not `image` or `circularImage`.
This needs to be done because the user can switch to an image shape later, as is happening in the issue.
Option `image` is only mandatory for the image shapes.
There is no unit test for this, because it would need a mock object for Image and I didn't succeed in creating/finding one.
* Network: Handle null data gracefully
During testing I discovered that passing `null` for network data leads to a thrown error.
This adds a guard to prevent it, plus unit tests for regression.

* Use mock canvas object replacing `canvas`
Fixes#3515.
A mock canvas object is added to the unit tests, which makes usage of module `canvas` voluntary.
The issue with `canvas` is that it requires an external dependency to `cairo`. This complicates setting up a develop environment for `vis.js`
- Removed `canvas` from `package.json`
- Added section to README.md with instructions on how to install `canvas` instead.
* Removed debugger statements
* Updates for review
* Fixes for review
* Network: Prevent crash when dataChanged is triggered during initial setting of options
Fixes#3562.
Options `hidden` and `physics` can emit a `_dataChanged` event within `setOptions()`.
If this happens when setting options during the initialization of the `Network` instance, this leads
to an error thrown, because there is no DataSet instance connected yet to the instance.
This bug was introduced in `v4.21.0`. Unit tests have been added for this case.
* Edited comment
Previous condition was too strict: if *any* node for the cluster was already clustered, the clustering would abort.
Current fix scans for already clustered nodes and proceeds with what is left.
* Network: Retain constraint values in label font handling
Fixes#3517.
Due to changed logic in the label font handling, the option values for `widthConstraint` and `heightConstraint` were overwritten.
The fix is in effect a reversal of two code lines: parsing constraint options should come *after* parsing (multi)font options.
Further changes:
- Additional 1-liner fix: constraint values were not copied for edge-instance specific options.
- Small refactoriing of `Label#constrain()` in order to separate concerns
- Added unit test for regression testing of this issue.
This leads to the curious observation that, while the actual change is two lines of source code, this resulted in a +-150 line regression test.
* Made unit test more linear, removed tabs
* Made 'enhanced subset' of unit test
* Removed TODO from comment
* Culled redundant nodes from unit test
Some browsers cannot handle very large DIVs so by default range DIVs
can be truncated outside the visible area. This change allows the use
of a new `limitSize` item option which disables this functionality,
allowing the creation of full-width DIVs.
I don’t see an existing test spec that covers RageItem.js so I’m
submitting without tests. However we’ve using Timeline in production on
a fairly large project with these changes in place for several months
and it works fine.
* Fixing a bug with the call to `repositionX`. The `items` collection is an object, not an array, so it cannot be iterated over using a normal for loop. Not repositioning the items causes the vertical stacking to jump around sporatically while scrolling.
* Update Group.js
* Network: Add extra check on null value during label handling
This fixes an oversight in #3486. Unit tests added, not only for null labels, but for all weird label values I could thing of.
* Enhanced unit tests, adjusted label check
* - Added support for vertical scrolling while the timeline is focusing on an element, both for animated and non-animated calls of focus
* - Adjusted item offset calculations to use the item parent
- Turned on animation for the focus in the example
- Updated function documentation
* - Fixing lint issues
* - Added documentation for the new 'frameCallback' parameter of 'setRange'
- Fixed the documentation on 'setRange' for the 'callback' parameter
- Fixed code not meeting style guidelines
* - Updated the example for "setSelection" to be more clear about what the example buttons do. Focus the language to be more consistent with that fact that the demo uses "setSelection"
* - Added support for stacking items within individual subgroups while subgroupStack is on
* - Adjusted location of visibility check to cover subgroup stacking
* - Fixing linting issues
* - Updated subgroup stacking to optionally take a 'subgroupStack' parameter of "true", which enables stacking in all subgroups
- Fixed code to meet style guidelines
- Updated documentation
* Small refactoring in Label._drawBackground()
* Added size calculation to Label, basic framework for detecting click on label.
* First fully working version of label click.
* Put in extra checks, refactored visibility of labels for more general usage.
* Final fixes to code; added to example and in docs
* Adressed review comments
* Add next attempt to fix Travis unit test bug
* Addressed review issues
* Network: Adjust documentation for arrows.middle.scaleFactor
Addendum to #3474.
Updated the documentation, so that users can know about flipping the middle arrow with a negative scale factor.
* Adjusted text for review
Fixes#3483.
If `shape: 'image'` is defined as option, this was used for initializing hidden cluster nodes during layout initialization.
However, because no image is being passed, this led to an exception.
This fix prevens shape `image` from being used for hidden cluster nodes. In addition, some extra fields for these nodes are
now overridden for some performance improvament.
* The next fix on Travis unit test failure
This is the next escalation on the war against the Travis unit tests failing (which came into being by yours truly).
By accident, I could recreate the unit test failure on my development machine. This led to a more directed effort to
squash the bug.
The insight here is that test `(window === undefined)` fails, but `(typeof window === 'undefined`)` succeeds. This undoubtedly has to do with the special status `window` has as a global object.
Changes:
- Added check on presence of `window` in `Canvas._requestNextFrame()`, fixed local source errors.
- Added catch clause in `CanvasRendered._determinePixelRatio()`
- small fix: raised timeout for the network `worldCup2014` unit test
* Preliminary refactoring in utils.js
* Added unit tests for extend routines, commenting and small fixes
* More unit tests for extend routines
* - Completed unit tests for extend routines in
- Small fixes and cleanup in `util.js`

* Added unit tests for known font options
* Interim save before trying out another proto chain strategy
* Fixed problem in first example #3408
* Removed silly file that shouldn't be there
* Added unit test for multi-fonts
* Comment edits
* Verufy unit tests, small adjustments for groups
* Further work on getting unit tests to work. PARTS NEED TO BE CLEANED UP!
* Further tweaks to get unit tests working
* All unit tests passing
* Fixes due to linting

* Add endpoint 'bar' to Network
Fixes#3412
- Adds class `Bar` and handling to `EndPoints.js`
- Adjusted `options.js` for endpoint, minor code changes
- Added to example `network/edgeTypes/arrowTypes`.
- Added to edges documentation
* Grumbl fix travis unit test yet again. Go die already!
* Network: Fixes sorting on Layout sorting, refactoring.
Fix for #3403
Chromium has divergent behaviour on sorting of `undefined` values, a check has been added for these.
The fix itself is small, it adds a check on `undefined` in the sorting function(s).
In addition:
- Fixed off-by-one error on tree index
- Refactored away checks on visibility by replacing `_isVisible()` with a Strategy pattern for direction
The latter removes a long-standing eyesore in `LayoutManager`; it's probably also faster.
There is some hope that these fixes will improve the hierarchical layout initialization, which has had
problems for quite a while.

* Add next attempt to fix Travis unit test bug
* Fix unit test - timeout
