5// all targets that support loads of the field types.

14// so that we can confirm that the functionality works in the
15// read-only case as well. The reason we are using a `RWByteAddressBuffer`
16// is because of limitations in the `render-test` app, and if
17// those limitations get fixed, we should switch this code.
