The font caches can only be used from a single thread at a time.
QFontEngineFT for instance, uses a global static thread storage
which is accessed on releasing and creating engines, and this
causes a crash if the font engine is created on one thread and
released on another.

We use the updatePolish() function to make sure the caches are
empty before entering updatePaintNode(), and then we invalidate
the cache again after updatePaintNode() is done.

Calculating the height of the line using ascent + descent seems
inaccurate, since the result will not match what ends up being
drawn. QQuickTextEdit uses instead QTextLine::height() for the
same function, and this works correct.
Since there seems to be no reason to reinvent how to calculate the
height when the line already has a function for that, and since the
result also seems to be wrong, we change the implementation to
use QTextLine::height().

Before commit fb339b21

 relied on the simple
transparent rectangle node to remain invisible. After that commit we used the
regular rectangle node, which doesn't seem to like toggling the color between
transparent and solid black and therefore the cursor was always visible.

As advised by Gunnar this patch implements a much simpler logic: When the
cursor is supposed to be invisible, we just don't create a scene graph node for
it anymore.

The value for acceptableInput was being calculated every time the
property value was read. This can lead to situations where the value
returned from successive property reads is different even though no
acceptableInputChanged() signal is emitted between the two calls.

This can be seen during QML component construction where emission of
the changed signal is suppressed until the component completes and the
value of acceptableInput changes as the other properties are set. If
the property is read during binding evaluation an intermediate value
can be seen and the QML engine will not re-read the property until
after the changed signal is emitted. This doesn't happen until the true
value of the acceptableInput property is toggled.

Fixed by changing the property getter to returned the precalculated
value of acceptableInput and ensuring that this value is set when
correctly.

See the task for the full reasoning behind this patch.

The threaded renderloop has been refactored to have one window per
thread. This is mostly a simplification of the current code path where
for loops over multiple windows are turned into if (window).

The QSGContext has been split into two classes, QSGRenderContext
for which there is one per OpenGLContext.

The rest of the patch is name changes and a couple of cleanups
in the hopes of simplifying this change.

Add dragType enums with values of None, Automatic, Internal (default).
Setting to Automatic allows startDrag to be called automatically.
Setting to Internal (default) retains old behavior.

Add mimeData to Drag item to enable external drags.

Call startDrag to start drag manually or change from internal drag to
external drag. Added events dragStarted and dragFinished that get
invoked from startDrag.

Mime data must be specified in the mimeData property as
mime-type / data pairs.

Moved QQuickDrag from qquickmousearea* files to qquickdrag* files to
reduce header interdependencies that caused linking errors in other
modules and also to improve code organization.

Allow DropArea to receive and process external data.

Introduced new variable containsDrag to QQuickDropAreaPrivate. This
replaces mimeData which was previously being used to determine if a
drop operation was currently occurring. The problem was that mimeData
was being externally destructed.

Also introduced accessor methods for getting color, html, image, text,
and urls out of the drop. This facilitates dropping of external data of
those types onto a DropArea.

Added example quick/externaldraganddrop.
