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.

Q_DECL_OVERRIDE (which expands to 'override' for supported compiler)
helps to declare the intent (that it is an overridden function) and
force compilation error when there is no such virtual function in the
base class.
The examples should show the best practice of having it, as it may save
the programmer quite some time in case of change of API or typo in the
function name or arguments.
This change was done automatically with
clang-modernize -add-override -override-macros
And fixed MSVC compilation by removing inline for TorrentViewDelegate::paint

Previously resizes along with the animation was implemented using queued
signals and slots, potentially causing a huge lag between the size of
the window and the rendered contents. Now the animation is always driven
by the rendering thread and is triggered based on the window's
isExposed() status.

The example was creating a new timer on every expose event, which
quickly leads into massive excess of timeout signals.
Fixed by only creating one timer.

Rename QGuiGLFormat to QSurfaceFormat, and make QWindow sub-class of
QSurface and QPlatformWindow sub-class of QPlatformSurface, instead of
having QPlatformGLSurface accessor in QWindow.
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.
