Description
Added error handling for requestAdapter example call.
Motivation
See https://bugzilla.mozilla.org/show_bug.cgi?id=2008734
Firefox seems to throw during the
navigator.gpu.requestAdapter()call when WebGPU is disabled by a blocklist, so I think it's better to be explicitly demonstrate this behaviour here. We used this snippet to feature test webgpu support and fallback to webgl if it wasn't supported, so this change in Firefox broke some of our sites.Additional details
