enable WebGL acceleration

[KonradHoeffner]

What new feature do you want?

Cytoscape 3.31.0 will add experimental WebGL support, see cytoscape/cytoscape.js#3305.
When that is released, try if the features are enough to cover our use cases.

[KonradHoeffner]

The GPU feature is now merged, see cytoscape/cytoscape.js#3314 and 3.31.0 is out now, so the experiments can begin!

cytoscape/cytoscape.js#3320 is fixed now by the cytoscape.js devs, waiting for the release 3.31.1 now.

3.31.1 should be out soon.

3.33.1 is out now even, so we can try again.
