WheelEvent conversion is currently doesnt treat full ticks and partial ticks the same way. This appears to have been done to support wheel-events emitted by DRT. This should be cleaned up so all wheel-events are treated the same, and DRT emits correct events. The problem is in particular to distinguish better between wheel-delta and pixel-delta which are often confused, and happens to be identical on some other platforms.
