+/// A utility to do buffer-swapping with.

+/// Use `src` to read from and `dest` to write to, and after actually changing data, call [Buffers::swap()].
+/// To be able to repeat the process, this time using what was `dest` as `src`, freeing up `dest` for writing once more.
+///
+/// Note that after each [`Buffers::swap()`], `src` is the most recent version of the data, just like before each swap.
