Display an error message if WebGL is not available

[vekin03]

Describe the feature

If WebGL is not available (or disabled), PSV simply displays a white background. Would it be possible to display an error message instead?

I've seen in the ThreeJS documentation that it already offers everything we need (check if WebGL is available + display an error message).

Alternatives you've considered

It's possible to implement it ourselves when using PSV, but I think it would be more logical to have this feature as standard.

It's easy to forget to do so, and not all webmasters are aware of this problematic :-)
