fc5482cac6 Support pinch zoom gesture in the Mandelbrot example
Used QGesture for this as per the gesture example.
Moved the help and info text to separate lines.
Enabled word wrap to prevent text going off screen.

As a drive-by, the code to center the window at a size that's a fraction
of the screen is replaced with a simple sizeHint() override. The user
should have control over placement, particularly now that it should be
placed manually onto a touchscreen if the user has one.

0e69349f6f Brush up the mandelbrot example
The example refines the image by running a number of passes
with increasing number of iterations, which is not really
visible to the user. Set an informational text string on
the generated image which provides this information
along with the elapsed time.
The idea is to do the same to the corresponding
Qt for Python example to have some sort of speed comparison
for number crunching.

Add a command line option for the number of passes.

Make the window a bit larger to accommodate the
information.

1b7ce85a60 Remove usages of deprecated APIs of QWheelEvent
- Replaced the usages of deprecated QWheelEvent::delta() and
  QWheelEvent::orientation() with QWheelEvent::angleDelta().
  In most of the examples it is acceptable to use only the vertical
  component of angle delta.

- Made the docs APIs to build conditionally, based on the
  deprecation version.

4d88d79aa5 Update usage of QFontMetrics::width() to new API
QFontMetrics(F)::width() has been deprecated and is replaced by
horizontalAdvance(). This updates all usage of it in tests and
documentation.

It is worth noting that many or most of the usages of
QFontMetrics::width() probably intended to use boundingRect().width(),
but since it currently works, I have not looked into that, just
replaced the function name mechanically.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

cf8f369f85 Move Qt Core examples under a common subdirectory
Qt Core examples were scattered into several subdirectories under
qtbase/examples. This caused an issue with the example manifest
file generated by QDoc; it expects to find all examples under a
common directory in order to produde correct paths to the example
.pro files. Qt Creator will not find the examples without a valid
manifest file.

This change moves the examples and edits the documentation files
accordingly.
