https://blotter.js.org is not showing in Safari / macOS.
The console shows:

	ub (blotter-site.min.js:32:112974)
	(anonymous function) (blotter-site.min.js:32:354127)

@daslicht, @sergey-pimenov Your problems appear to be different so (months later, Im sorry) Ill offer some advice to each post:

@daslicht It looks like webgl failed to load in your browser. Note how the error itself is coming from Three.js. That's very early in Blotter's lifecycle and likely has nothing to do with Blotter or even ThreeJS but rather something wrong with your browser or system. However, I think the Three.js project is a better place to debug that issue: mrdoob/three.js#4927

@sergey-pimenov The issue with ImageData data lengths should now be fixed after the closing of #34.
