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)

It turns out that scrolling appears to be slow when using
non-mac mice with the carbon build. This patch introduces a
an acceleration algorithm that closer resembles the one
used by Cocoa.

Seems like I forgot to handle page scrolls.
Also did a small optimization
(see also 45f095b8970dc3c1b6f6e97fa2323654ba848288)

It turns out that we need to let singleStep keep its value
in qtextedit so that pushing the up/down buttons on the slider
works as they should. Moreover, overriding the behaviour in
abstract slider also makes QGraphicsView work out of the box.
Also added in the test fix suggested by Olivier.

A wheel event contain delta values that describe the rotation
angle the wheel was rotated (in 1/8 of a degree).
For some mouse devices (thinking of mac mighty mouse/trackpad)
the resolution is better than the standard 15 degrees. The Qt
docs describe how to deal with this. But abstract scrollbar does
did follow this recipe, but it does now with this patch.

All changes of this commit are #ifdef'ed in
QT_KEYPAD_NAVIGATION. Most desktop Qts won't notice
any change.
Navigating between QWidgets was not alwys a pleasure on
keypad devices. This commit fixes the navigation behavior
for some widgets, mostly itemviews.
Furthermore, it adds a 'directional' navigation mode. Until
now, the existing keypad navigation used the tab order
do go back and forth between widgets. The new mode is supposed
to provide a more intuitive navigation. It is the new default
mode on Symbian.
Screens (and their resolutions) become bigger, and also low
resolution screens can be used in landscape mode. That's
why the directional mode was requested.
Another popular request was to put some more convenience into
QSlider: If a (horizontal) slider has focus and the user presses
left/right, the value of the slider may directing change
without being selected (edit mode).
This commit also adds the manual test 'keypadnavigation'.
