Should objects expose the descriptor they were created with? #1498
Description
Today, there's no way to do "reflection" on an object to see what descriptor it was created with (or what the results of defaulting were, or see what fields were obeyed), with a few exceptions: GPUDevice.features, GPUDevice.limits, and GPUPipelineBase.getBindGroupLayout().
Should we reflect descriptors for other objects?
- Easy cases: buffer, texture, etc.
- Hard cases: bind group layout, bind group
Non-blocking because adding them is a non-breaking change.
