Description

I had to use "fragile-send-sync-non-atomic-wasm" feature in wgpu dependency sample to avoid a lot of issues related to the multithread support changes

Remaining issues

• egui targets wgpu 0.18.0 on master but they haven't made a release yet so this may be a blocker for rend3-egui
• imgui hasn't updated yet so may also present issues for rend3-imgui
