[Win32] Properly convert event coordinates in Tracker

[HeikoKlare]

The coordinates for mouse move events in Tracker are currently just scaled via pixel/point conversion methods. However, those are display coordinates which need to take the coordinate system specifics into account and thus have to be converted via the display methods for translating coordinates.

This change adapts the implementation accordingly.
