[locke-lunarg]

Now, win32 supports --fwo that set window position.

The other platforms don't. Here is a branch to support it on xlib, xcb and wayland.

But it didn't get test. vkcube and SaschaWillems's examples don't use xlib. The window position on xcb couldn't be changed. I don't know the reason. gfxr can't set Wayland window position.

FYI, gfxr doesn't capture if the application runs full screen mode or not. During replay, it checks if the replay resolution is the same to the screen resolution or not to decide if it runs full screen mode or not. It means although vkcube doesn't support full screen, it could still replay with full screen mode if the resolution is the same to the screen resolution. Plus, if it has multiple monitors, the screen resolution that gets by system could be the total of the all monitors.
