Instead of using a cursor width of null when a cursor
delegate is set, we should to use a value of 1.
Otherwise the rect we e.g return from cursorRect() will
be invalid. An alternative would be to use the width of
the delegate, but that was found to be controversial.

On iOS we saw a bug with this when telling iOS to position
text spelling popups underneath the cursor. Since the
cursor rect we got was invalid (zero-width), no popup
would show.

If an item grabs a touch that is currently being used for mouse pointer
emulation, the current mouse grabber should lose the mouse as mouse
events will no longer be generated from that touch point.

Example of what happens without this patch:
-User touches a MouseArea. It gets pressed.
-Some other item grabs that touch.
-This touch eventually ends.
-The MouseArea would still be pressed.
And what will happens instead after this patch:
-User touches a MouseArea. It gets pressed.
-Some other item grabs that touch.
-The MouseArea gets canceled and released
-This touch eventually ends.

This reverts commit 427646b8

.
It seems that it should have been more correct, but we are still not
shipping English translations, and static QString find_translation()
in qtranslator.cpp will return any language which is in
QLocale::uiLanguages() for which the translation file is found.
That is a long list on OSX.

Reverting the patch means find_translation() is not called in
such cases.  This change can be re-done whenever we are more sure
that the attempt to find a translation will succeed in finding a
sensible one, or fall back to not translating, rather than choosing
a language that the user didn't intend.

It can't be instantiated like a QML type, so it's actually better to
just document measureText() (which is the only way to construct objects
of this type) as returning an object containing some metrics for the
current font. This should have no effect on user code.

This solves the issue of the new TextMetrics type's documentation not
showing up. TextMetrics is a type that *can* be instantiated and is
more feature complete. It provides a declarative API for the functions
that take arguments in QFontMetrics.

This was merely a glitch in the grammar, I see no reason not to support this.
The semantics are like a const pointer in C++, the property itself is read-only
but the object pointed to has per-property defined read/write semantics.

In updateSize() we were trying to force relayouts for RichText
when the width changes by always setting widthExceeded to true.
But further down in the same function, we overwrote this
with textWidth() < idealWidth(), which doesn't work, because
both properties are the wrapped width of the document and
should only differ if the text cannot be wrapped properly.

The result was that when increasing the width of a Text element,
we would hit the optimization and skip the relayout.

Having a retina and non-retina screen connected resulted in getting
no output from QQuickRenderControl and QQuickWidget on the
non-retina screen.

This is caused by the fact that Quick is blindly calling
QWindow::devicePixelRatio(). This approach is wrong when using
QQuickRenderControl since the QQuickWindow does not have an actual
native window and so devicePixelRatio() merely returns some default value
which will definitely be wrong for one of the screens.

QQuickWindow::effectiveDevicePixelRatio(), which, via
QQuickRenderControl::renderWindowFor, supports the redirected case too.
