MEL is from a time before Qt supported pixel-precise scrolling, so it only has delta. The pixelDelta/angleDelta split is relatively new in Qt as well, at least it only works on X11 since 5.3.

Task Manager does a lot of event interception and handling which aren't feasible with pure MouseArea, I guess. Eike should know best.
