On Linux, just call the tick callback on every loop tick. This is much simpler, and should fix the issue with screen updates sometimes getting stuck waiting for an X11 event. Note that this was what used to happen (global state being checked on every loop tick) before the refactoring to use a GLFW event loop, therefore there should be no performance regressions, though we of course end up checking global state on every group of events on Linux, instead of only when something of interest happens. I suspect, to achieve the latter is going to require implementing a mutex/lock in the main loop to avoid races, which doesn't seem worth it.
