Summary:
For unused warps we always write zeros to `bary_img_grad`.
However it is possible that the warp is used, but only portion of the threads are used. In this case, for unused threads we do not write zeros to `bary_img_grad`.

For efficiency, `bary_img_grad` is created with `at::empty`, thus  those before mentioned entries, will still have uninitialized values.

This is not an issue, because the `render` function will never read those entries, however it is possible that the uninitialized values will coincide with `nan` and it will trigger a false positive detection in auto grad anomaly detection.  Please see more details in D60904848 about the issue.

Summary: In order to work properly with `torch.compile()`, we need to decorate any function that calls a custom C++/CUDA extension with `torch.compiler.disable` so that it knows to insert a graph break.
