Since we changed the behaviour for scrolling on mac to not
be restriced to an upper limit (pagestep), we need to adjust
the auto test accordingly

Fixed a bad merge in the QAbstractSlider::wheelEvent.
Modified an autotest to follow a change in behavior - scrolling with a
horizontal mouse wheel to the "right" means increasing the value.

Commit 46a3e518b3070c changed the behaviour of a wheel event of
a different orientation.
It works now no matter where the event was.

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)

...on mac. Since mouse wheel events are accelerated by the OS on mac,
we cannot multiply the delta with QApplication::wheelScrollLines,
since this will make scrolling behave far to fast. To change the
speed of wheel events on Mac, one should use system preferences.
This patch updates the test to reflect his difference.

Each version of Qt has its own set of autotests, therefore
preprocessor directives relating to obsolete QT_VERSION's
are not necessary.
