v1.1.0

Fix fullscreen redraw and column drag sticking bugs

- ScrollChanged handler now re-renders on viewport size changes
  (ViewportHeightChange/ViewportWidthChange), not just scroll position
  changes. Fixes maximize/fullscreen not showing new cells.
- Add safety net in PreviewMouseMove: detect released mouse button
  during drag to recover from lost mouse capture caused by visual
  tree churn during RedrawAll().
