Using the mouse wheel to zoom in the viewport while on a HiDPI device was zooming around the wrong anchor position. Other mouse events were using different logic to for the mouse position so I updated the wheel event processing to do the same.

This replaces PR #223 as it had gone stale and rebasing didn't work.
