Extend GPU texture format support with capabilities like render attachment, blending, multisampling, resolve and storage_binding.
Tier1 lets developers port existing content to the web without rewriting to use WebGPU’s lower capabilities. Tier2 supports storage textures formats that don't have support in base WebGPU, meet the need for Unity and various startups to port Unreal Engine to the Web. Tier1 is a dependency of Tier2. By exposing those capabilities as WebGPU features, developers can explicitly check for support and provide fallback solutions or alternative rendering paths when necessary.
