Fix issues with reverse axes

Moved the reverse axis handling to domains instead of simply mirroring
the painter. This fixes the following issues with reverse axes:

- QChart mapping functions returned unreversed values
- Bounding regions of series were incorrect
- Mouse events gave wrong positions
- Chart scrolling and zooming didn't account for reversed axes
