Offload Some Tasks To Secondary Thread

[IAGOnGithub]

Most, if not all, tasks seem to run on the same thread. While this is fine in many cases, some intensive tasks will cause the GUI to lag significantly as rendering is delayed. Ideally, this shouldn't happen. Some tasks should be offloaded to a separate worker thread to let the main thread (where application rendering takes place) run without significant interruptions.

This issue might be a duplicate. I searched "thread" in the issue tracker and nothing came up.
