fix an instance of bugprone-argument-comment

This new clang-tidy check complains when param names /*in_comments=*/
don't match up with the actual parameter name they're being passed to.
Sometimes this is benign, other times, actual bugs are found.

Since callees and the definition used `quad_layer_rect` here, flip the
decl to use that, too.
