Pull request overview
This PR addresses missing support for PrimitiveOffsetInfo-based offsets in render pipeline indirect draw methods, and extends indirect dispatch to accept raw GPUBuffers (aligning compute + render indirect APIs and adding runtime validation/warnings).
Changes:
- Add
PrimitiveOffsetInfo | numberoffset support (and stricterIndirectFlagtyping) fordrawIndirect/drawIndexedIndirect. - Allow
dispatchWorkgroupsIndirectto accept rawGPUBuffers, with consistent validation/warning behavior. - Centralize indirect offset/size validation into a new
resolveIndirectOffsetutility and add/extend tests + mocks.

Neat! 🐛🌊 I would just reconsider these warns, maybe they can just be a part of JSDocs?

If somebody uses this api, they will get 60 warns per second. I think it would be fine if it only appeared once, but we don't yet have the logging infrastructure to do this.
Maybe we could suggest using typegpu buffers instead? As a way to silence this warn

Good point, I will put this in jsdocs

Or just like we do with raw number, I will provide quick fix how to suppress warns
