Currently picom fails at register_cm(), which is before print_diagnostics(), so we don't see anything. This commit makes sure we keep going when there is another compositor already running. However, in this case we need to be careful to not take the overlay window, otherwise a poorly implemented compositor (for example, picom) will stop working. Also restructured the target window initialization logic and added some comments explaining the logic. Fixes #333
