I posted an example in the other thread of how a browser might present
a known WebGL issue, an unobstrusive infobar at the top of the tab :

This web page could not initialize WebGL (what is this?) because of
obsolete graphics drivers.      [Upgrade driver now] [Do it later]
[Forget it]

In other words, it could be indeed something similar to what most
browsers already do when a plugin (eg Flash) is not available and
needs to be installed, or when the browser requires user action to
authorize a script feature (eg. geolocation API).

User-friendly troubleshooting of WebGL is something that browsers do
not handle at all currently, we will hopefully improve this situation.
