Get window size

Technically it's possible to change window mode & window resolution during runtime. It's a bit buggy though at the minute.

I did it get working to change between fullscreen and window (resized) via checkboxes without restart. Problem seems to be Resolutions which are "special". Sometimes after returning to fullscreen it gets messed up and only a restart solves it.

Yeah, that's the buggy bit I was referring to. If you simply toggle between window & fullscreen modes without adjusting the window resolution then it shouldn't mess up when switching back to fullscreen mode. For some reason it messes up the surface area scaling when you manually update the window resolution. Hopefully David will sort it out in a future build.

im curious if it would correct that bug if we set the window size back to screen monitor resolution before returning to fullscreen...
