    testsuite: Make all gesture test touches happen in the middle of the window
    
    The event coordinates are (so far) irrelevant to what we are testing here,
    just make all events happen in the middle of the window in order to ensure
    all widgets receive it. More importantly, avoid using fixed pixel distances,
    since we don't get guarantees about window sizes.
    
    Fixes the gestures testsuite on X11.
