Description
I discussed this with Alex, and it seems like we might be able to remove the call to `clear_atlas_region` when deallocating images. Since new images can just override the area they need, it shouldn't be necessary to explicitly clear previous images.

Research direction
Start in the vello_hybrid image-deallocation path and locate the call to clear_atlas_region. Inspect how newly allocated images overwrite atlas areas and verify that removing the clear does not leave stale pixels in rendered output. Done means the unnecessary clear is removed without changing rendering behavior.
