One drawback to trying to predict the number of threads that will be used in the `task_graph` is that we are only sure of the number when the threads are running. Using `BLI_task_parallel_range` allows the driver to choose the best thread distribution through `parallel_reduce`. The benefit is most evident on hardware with fewer cores.
