5786ac12f0 Fix hellowindow example
It seems this example never worked as expected.
It has a 'multiple' option which should show extra
windows with rendering taking place in different
thread, however although render is moved to other thread
render() function was never called in that thread.

Fix following things:
 * make rendering in other thread
 * stop requestUpdate if nothing is exposed
 * add timer so animation works at the same speed despite
   of number of windows (renderer B renders two windows)
 * wait for render to finish before triggering requestUdpate
 * remove mutex where not needed

Pick-to: 5.15

19b0ce5daa Change almost all other uses of qrand() to QRandomGenerator
The vast majority is actually switched to QRandomGenerator::bounded(),
which gives a mostly uniform distribution over the [0, bound)
range. There are very few floating point cases left, as many of those
that did use floating point did not need to, after all. (I did leave
some that were too ugly for me to understand)

This commit also found a couple of calls to rand() instead of qrand().

This commit does not include changes to SSL code that continues to use
qrand() (job for someone else):
  src/network/ssl/qsslkey_qt.cpp
  src/network/ssl/qsslsocket_mac.cpp
  tests/auto/network/ssl/qsslsocket/tst_qsslsocket.cpp

02b7ec05d5 Be (somewhat more) consistent about the value of pi
Use M_PI (and friends), where possible, in favor of hand-coded
approximations of various (in)accuracies.  Where that's not available
(e.g. fragment shaders), use the same value that qmath.h uses for
M_PI, for consistency.  Replaced math.h with qmath.h in places that
defined a fall-back in case math.h omits it (it's not in the C++
standard, although M_PI is in POSIX); or removed this entirely where
it wasn't used.

Reworked some code to reduce the amount of arithmetic needed, in the
process; e.g. pulling common factors out of loops.  Revised an
example's doc to not waste time talking about using a six-sig-fig
value for pi (which we no longer do) - it really wasn't relevant, or
anything to be proud of; nor did the doc mention its later use.

0ff3e7d155 Make hellowindow multi display capable on embedded
Platforms like eglfs allow a single window per screen. Thus the behavior of
--multiple is not suitable since it tries to open multiple windows on the
primary screen. Instead, introduce --multiscreen.

Add also --timeout to quit the app after 10 seconds. This is essential on
platforms that do not have windows with decorations that can be used to
close windows.

With eglfs' kms/drm hooks, starting with --multiscreen will now show a
rotating logo on all connected displays, with some random background color.

f4ae4f41b0 hellowindow: Set all the state for each frame
Trying to be smart and minimizing the amount of GL calls per frame
to provide a good example was a mistake (in a way): There are
components, like the eglfs mouse cursor, that change the context state.
To make sure the example work in these cases, set the state upon
each frame.

611558d877 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.

1e18df9c73 Extend QOpenGLFunctions with GL1 functions
This introduces the ability to indirectly invoke all common GL1-GLES2
functions via QOpenGLFunctions. The GL1 functions are not yet resolved,
since this would not work anyway when linking to an OpenGL implementation
directly. However this may change later but that will be a completely
internal change without affecting any public APIs.

Also migrate some of the opengl examples to use QOpenGLFunctions for
everything. Once dynamic GL loading becomes available on some platforms,
these examples should continue to function without any changes since they
do not anymore invoke any OpenGL functions directly.

by the rendering thread and is triggered based on the window's

cd34da5426 Rename all QWindow properties that have "window" in them
windowTitle, windowModality, windowIcon and so on are named that way
to be similar to the ones in QWidget.  However QQuickWindow inherits
all of the declared properties, and we would like to have shorter
property names in QML.  If you are working with a Window then it's
obvious the title property is the window title.  Unfortunately,
there must be patches in many other modules which depend on this one.
In order to avoid the need to merge them all at the same time,
there is also patch https://codereview.qt-project.org/#change,39001
which temporarily adds backwards-compatible accessors, which can be
removed after the other modules are able to build without them.

We should not rename windowState to state, because in QML, state
usually drives the state machine for animation transitions etc.
(although QWindow is not an Item, a user might get confused about it).

c3da77798b Added workable QScreen API on top of QPlatformScreen.
QPlatformIntegration::screens() no longer has to be implemented,
implementations should call QPlatformIntegration::screenAdded() for each
screen instead. This is for being able to support adding screens at
run-time later on, by connecting it to a signal in QGuiApplication.

The QGuiGLContext API has changed a bit, by not sending in all the
parameters in the constructor but instead having a create() function.
The createPlatformGLContext() factory in QPlatformIntegration takes a
QGuiGLContext * instead of a QSurfaceFormat and a share context, similar
to how the window and backing store factory functions work.

The XCB plugin has experimental support for connecting to multiple X
displays simultaneously, creating one or more QScreen for each.

4a189c188c QWindowContext / QWindowFormat refactor.
To enable having a single GL context used for multiple drawables we need
to de-couple the context class a bit more from the window class in the
plugin API. Now contexts are created stand-alone based on a GL format
and a share context, and when calling makeCurrent() a desired surface
is specified. This maps well to GLX, EGL, Cocoa, AGL, and WGL, which all
support this use case.

QWindowContext is renamed to QGuiGLContext, and QWindowFormat is renamed
to QGuiGLFormat. We have the ability to introduce a pbuffer or similar
other offscreen GL drawable abstraction in the future.
