Fix msaa in QOpenGLWidget

Take the correct number of samples from the widget's context, not the
tlw's context.

The original implementation did the blit only after paintGL(). This is
not sufficient for applications that override paintEvent() and do QPainter
calls in there (e.g. the 2dpainting example). Therefore the approach is
changed to perform the resolving of the samples in a function that is
invoked by QWidgetPrivate every time a paint event is sent.

qdoc: Distinguish between QML property and attached property

A recent change in qtdeclarative (60ed6a43) added an attached
property 'Window' to Item type, with property names identical
to the ones already available in Window. This caused QDoc to
report warnings for duplicate documentation for QML properties,
because there was no distiction between a QML property and an
attached property.

This change fixes the issue by:
    - Allowing identical names for \qmlproperty and
      \qmlattachedproperty
    - Using distinct URLs/UUIDs/anchor references for them
    - Marking attached properties with '[attached]' qualifier
      in 'All Members' page.

This doesn't solve the issue of disambiguating between a
similarly named QML property and attached property when
linking from an external location. However, these can be
solved with the help of the \target command.

Modernize the OpenGL examples

Change them to use QOpenGLWidget and QOpenGLTexture.
Advocate also the usage of VBOs.

Hopeless examples, that rely on the fixed pipeline and will
not compile or work in ES and dynamic builds, are moved to
a "legacy" directory. The documentation pages for these are
removed. This long due change avoids the confusion newcomers
experience when trying to get started with Qt 5 and OpenGL.

hellowindow's behavior is changed to open a single window only
by default. The old default behavior, that opened three windows
on platforms that supported both MultipleWindows & ThreadedOpenGL,
can be requested by passing --multiple. --single is removed since it
is the default now. This plays much nicer with drivers that have
issues with threading.

In addition, say hello to hellogl2.

This is the old hellogl example updated to use QOpenGLWidget and
OpenGL 2. It also has a mainwindow with multiple (un)dockable widgets
containing the OpenGL widgets. This helps testing the behavior when
the top-level of the QOpenGLWidget changes and provides a very
important example of how to do proper resource management in this case.
(must use aboutToBeDestroyed() of the context, since the context goes
away and is replaced by a new one on every dock/undock)

As a bonus, the logo is now real 3D, no more orthographic nonsense.

Launch with --multisample to request 4x MSAA.

Launch with --coreprofile to request 3.2 Core. In this particular example
the shaders are present in both versions and there is a VAO so the application
is functional with core profile contexts.

Make the expose region local on all platforms

QExposeEvent::region() reports a region in a random coordinate system.
The behavior is undocumented and the platform plugins do different things.

xcb, offscreen and ios are correct. These set the region in local coordinates,
which is the most logical interpretation of the expose region.

windows is almost correct, except for one occurrence.

cocoa and others need changes: passing in geometry() as the exposed region is
always wrong.

The patch documents the expected behavior both for QExposeEvent and
internally in QWindowSystemInterface. The problematic plugins are fixed to
use local coordinates.

Some tests are not fully functional due to errors in the file
implementation (See QTBUG-40588).

QSettings::SystemScope translates to a roaming container on WinRT,
meaning that settings stored inside there should be uploaded and
shared among devices. However, this is untested so far.

the order of keys. This has been done on some locations only so
far, but needed to be done on more places for WinRT.
