Support pixel-based deltas as well as sending
dx and dy values in the same event. Keep source and
behavior compatibility with Qt 4.
New API:
QPoint pixelDelta() const
QPoint angleDelta() const
Deprecate delta() and orientation().
Both pixel-based deltas and combined updates are
necessary for smooth trackpad-based scrolling on
OS X.
Qt 4 compatible behavior is achieved by sending an
extra wheel event in cases where the initial event
has a combined dx and dy update. This extra event
sends dx in delta() and orientation(), with pixelDelta()
and angleDelta() set to null.
Modify the Cocoa implementation to provide pixel
deltas. It is expected that not all platforms can
provide these. Angle deltas will always be available.

As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

QCocoaWindow now gets resize events from QNSViev
and does not require a NSWindow. QWindow instances
can now be inserted in NSView hierarchies. This is
useful for Qt-as-a-plugin use cases and is needed to
implement QMacNativeWidget for Qt 5.
