Clip by bounding delegate size instead of Item.clip.
Summary:
- "Never enable clipping on a delegate." (http://doc.qt.io/qt-5/qtquick-performance.html) It mucks with the scene graph's ability to optimize draw order.
- Also means window rects don't get cut off, their frames are nicely bounded. Technically this is a small information loss - you can't tell from the pager anymore when a window is going out of screen bounds - but it's visually rather pleasing.
