* 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: 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
* 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
* 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
