Implement support for wheel delta with finer resolution than 15 deg.
At the moment, Qt, in many places, does not really understand that a mouse wheel, or touch pad, might operate on a much higher granularity than 15 degrees (that is, a delta of 120). This is clear disadvantage on mac, since the mighty mouse, and track pad, got a resolution that is close to 1 degree. This is called pixel scrolling. This patch first and formost changes the implementation of QAbstractSlider::wheelEvent to _really_ understand what to do when delta is less than 120. Rather than accumulate delta until 120 is reached, then scroll with a value equal to: offset * step * QApplication::wheelScrollLines (default = 3), we multiply offset directly, before waiting for 120. This means that event tough offset is below 120, multiplying it with wheelScrollLines and step will very often give a value over 120, menaing we can scroll much earlier and _much more_ fined grained. This also fixes some auto tests that was ifdeffed out because of specialised mac code written inside this function from before. (NB: we still plan to introduce a new event for pixel scrolling, perhaps for Qt-4.7) Rev-By: Andreas Rev-By: denis
