All current examples are based off of one thread. Judging by the incomplete update method in controlgallery, it might already be planned.
It would be super helpful to have at least one example do work with multiple threads.
I'm attempting to emulate what the pure C version does, but I can't seem to share any Controls across threads because they don't implement Send or Sync. (I'm not sure if they should, or if Controls should be reconstructed based on their usize "handles"?)
