QEventPoint does not have an accessor to get the QPointerEvent that it
came from, because that's inconsistent with the idea that QPointerEvent
instances are temporary, stack-allocated and movable (the pointer would
often be wrong or null, therefore could not be relied upon).
So most functions that worked directly with QQuickEventPoint before
(which fortunately are still private API) now need to receive the
QPointerEvent too, which we choose to pass by pointer. QEventPoint is
always passed by reference (const where possible) to be consistent with
functions in QPointerEvent that take QEventPoint by reference.

QEventPoint::velocity() should be always in scene coordinates now, which
saves us the trouble of transforming it to each item's coordinate system
during delivery, but means that it will need to be done in handlers or
applications sometimes.  If we were going to transform it, it would be
important to also store the sceneVelocity separately in QEventPoint
so that the transformation could be done repeatedly for different items.

At this time, there are not yet any specialized handlers to
do anything specifically with tablet events; but we demonstrate
how to use HoverHandler to detect the type of stylus in use,
and how to use PointHandler to draw on a Canvas.

Unfortunately, events of types TabletEnterProximity and
TabletLeaveProximity are not delivered to the window, only to
QGuiApplication.  So HoverHandler can detect when the stylus is moved
out of its parent Item (as long as it's still hovering over the tablet
surface), but cannot detect when the stylus leaves the tablet completely.
In Qt 5 that would require a custom application subclass
(see qtbase/examples/widgets/widgets/tablet/tabletapplication.cpp).

Also, QQuickItemPrivate::setHasCursorInChild() was unable to check
the QQuickItemPrivate::hasCursor variable, because the function
argument hasCursor was shadowing that, even though the comment
"nope! sorry, I have a cursor myself" hints that the intention
was to check that.  So this change exposed a problem there, and
we have to fix that too, in order to keep the tst_qquickwindow::cursor()
test passing.

[ChangeLog][Event Handlers] Pointer Handlers now have a cursorShape
property to set the cursor when the handler is active and the mouse is
hovering, and restore to the previous cursor when the mouse leaves.

It doesn't make sense to show hover feedback after releasing a
touchpoint just because the core pointer cursor happened to move along
with the touchpoint, so we explicitly set the hovered property to
false when the touchpoint is released.  However the next mouse movement
will set it back to true again if the mouse cursor is still inside.

This is especially important for touchscreen-based haptic interfaces:
any hover feedback should be shown when a finger is dragged into an
interface element and hidden again when the finger is released.

It was intended to inherit most of the docs from SinglePointHandler; but

Required a change to a #include; qquicksinglepointhandler.cpp was (at
least on Android) only seeing QQuickSinglePointHandler as a forward
declaration, so dereferencing it was a problem.  The header that
defines it does #include the one it replaces here.
