7c59c5ed13 Examples: remove OpenGL code paths from painting examples
The extra code for using the OpenGL paint engine is significant enough
to be distracting from what the examples are supposed to show. If we
want to show how to use QPainter on an OpenGL widget, then we can make
dedicated and documented examples for that, in the OpenGL category. And
we have such examples in the Qt OpenGL module anyway.

As is, the examples feel more like manual tests of the OpenGL paint
engine; if we need more coverage there, then we can add it there.

92185d417d Fix BASE argument of qt_add_resources
The BASE argument of qt_add_resources now denotes the root point of the
alias of the file.  Before, BASE was merely prepended to every file that
got passed to qt_add_resources.

Old behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "images/button.png")

Alias is "../shared/images/button.png", and pro2cmake generated
QT_RESOURCE_ALIAS assignments to fix this.

New behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "../shared/images/button.png")

The alias is "images/button.png".  No extra QT_RESOURCE_ALIAS assignment
is needed.

The new behavior is in effect for user projects and for Qt repositories
that define QT_USE_FIXED_QT_ADD_RESOURCE_BASE.  Qt repositories will be
ported one by one to this new behavior.  Then the old code path can be
removed.

638ac41293 CMake: Fix painting examples to build as standalone projects
The examples use an intermediate object library to avoid duplicate
file compilation. The examples worked when built as part of Qt
because the shared directory was always added, and Qt::OpenGL is
available implicitly.

Change each project to add_subdirectory(../shared) if the object
library is not available, thus making the examples build as standalone
projects.

Call find_package inside the shared project, to ensure the Qt packages
are found.

Create an alias called 'painting_shared::painting_shared' and link
against that to ensure that any failure is caught at configure time
rather than build time.

Adapt the pathstroke example to use the object library.

Comment out the code for the OpenGL scopes, because it's handled
by the object library.

Make sure the OpenGL dependency is public.
Make sure to run moc and compile the OpenGL specific files as well.

efa9998521 Fix compiling of examples on Android
* Simplify add_qt_gui_executable() to not require WIN32/MACOSX_BUNDLE
  but provide it implicitly. It's redundant :)

* When on Android, build a module (shared library), just like qmake.
  This requires an additional library destination in the install() call,
  but that's ignored on other platforms.

* Fix typos in the android deployment generation settings function

* Use the correct cache variable to determine whether we're inside a Qt
  build or not. Right now this only works inside Qt builds anyway as
  QtPlatformAndroid.cmake is not publically accessible.

6732fa3a29 Fix linking of examples
Provide add_qt_gui_executable() as function in our public API that takes
care of automaticWinMain linkage. We can use this in the future to
encapsulate similarplatform-specific behavior and adjustments, such as
module generation onAndroid.

In order for the examples to see the function in Qt5CoreMacros, three more
additional fixes were required:

    * Do the build_repo_end() call _before_ attempting to build the
      examples, as we need the build_repo_end() to include QtPostProcess
      and complete the creation of all the target config files.
      Otherwise the find_package() calls in the examples see something
      incomplete.

    * Add more QT_NO_CREATE_TARGET guards

    * Always call find_dependency on the dependencies, regardless of the
      target creation mode. This way a find_package(Qt5 COMPONENTS
      Widgets) will still load Qt5CoreMacros.

83a5694dc2 Update copyright headers
Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Outdated header.LGPL removed (use header.LGPL21 instead)

Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)

Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

3b0c2b7c1b Examples: Add Q_DECL_OVERRIDE to overridden functions
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
