1) No WebGL framework in existence handles context lost, or will handle it
in anything like the forseeable future, if at all, ever.
2) It might just be nigh-impossible to write any kind of framework that can
3) Requring the average interested WebGL developer (or even the average
framework writer) to deal with this, is relegating the writing of WebGL
code to the elite of the elite, and even so, their code won't be pretty,
reusable or understandable.
4) No, none whatsoever, WebGL demo/application beyond the hello-world
equivalent handles context-lost so far, I posit, it's impossible anyhow for
anything slightly non-trivial.
So I know I can rant whatever I like, and the problem's not gonna go away.
But you can introduce context-lost all you want, the problem's *also* not
