It is possible for a BufferSize of 0 bytes to trigger validation warnings as such buffers still need to get bound to their pipeline. The standard vello engine (src/engine.rs) handles this when a BufProxy is requested by setting the requested size to at least 16. This is now handled by the encoding crate by selecting a buffer size that can fit at least one element.

This has been a source of many problems so thanks for making it actually correct!
