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.

We introduced WrapOpenGL to link against either desktop GL or GLESv2
depending on the GL feature in QtGui. This works "fine", with two
caveats:
(1) find_package(WrapOpenGL) must be called after
find_package(Qt5Gui) in order for the feature check in
FindWrapOpenGL.cmake to work. That's error prone.
(2) More and more places are popping up, in particular examples,
where GL linkage is required due to inline functions in Qt that
forward to GL functions - such as on Android.
This in particular explains the qmake behavior of making the GL
linkage (desktop _or_ GLES) a public dependency of QtGui, so only
Gui linkage is required.
Those two aspects combined are the nail in the coffin of FindWrapOpenGL
and it would seem much easier to simply make the Desktop GL vs. GLES
decision once in Gui's CMakeLists.txt and let Qt5GuiDependencies.cmake
propagate this well. This allows us to get rid of plenty of special
cases as well.

This change introduces a new function called qt_find_package()
which can take an extra option called PROVIDED_TARGETS, which
associates targets with the package that defines those targets.
This is done by setting the INTERFACE_QT_PACKAGE_NAME and
INTERFACE_QT_PACKAGE_VERSION properties on the imported targets.
This information allows us to generate appropriate find_dependency()
calls in a module's Config file for third party libraries.
For example when an application links against QtCore, it should also
link against zlib and atomic libraries. In order to do that, the
library locations first have to be found by CMake. This is achieved by
embedding find_dependency(ZLIB) and find_dependency(Atomic) in
Qt5CoreDependencies.cmake which is included by Qt5CoreConfig.cmake.
The latter is picked up when an application project contains
find_package(Qt5Core), and thus all linking dependencies are resolved.
The information 'which package provides which targets' is contained
in the python json2cmake conversion script. The generated output of
the script contains qt_find_package() calls that represent that
information.
The Qt5CoreDependencies.cmake file and which which dependencies it
contains is generated at the QtPostProcess stop.
Note that for non-static Qt builds, we only need to propagate public
3rd party libraries. For static builds, we need all third party
libraries.
In order for the INTERFACE_QT_PACKAGE_NAME property to be read in any
scope, the targets on which the property is set, have to be GLOBAL.
Also for applications and other modules to find all required third
party libraries, we have to install all our custom Find modules, and
make sure they define INTERFACE IMPORTED libraries, and not just
IMPORTED libraries.

It seems there is a subtle bug in the Wacom tablet drivers for Windows that is
triggered in the very particular case where the running executable is named
"tablet.exe", regardless of its installation path. It causes WM_POINTER*
messages not to be delivered to the application, initially, but only after the
application's window is reselected, after another application's window had
been selected. It happens at least on Windows 10 systems with Wacom Bamboo
tablets and drivers, and was reproduced with non-Qt-based applications also.
It looks like a bad compatibility setting that makes "tablet" a cursed target
name for applications using tablet functionality. It seems older versions of
the drivers used to contain an executable with this name, although it seems to
be absent in newer versions. Unfortunately, the Qt tablet example uses this
name, which breaks it when used with upcoming WM_POINTER* messages support.

When reading an HTML file with <H1> for example, we still set the font
size as before (that's how it always was done),
but now it remembers that it came from an H1 tag, so it writes
<h1 ...><span font-size:xx-large ...> ... rather than
<p ...><span ...> ... This will help with the upcoming Markdown
format, where heading level is saved but the font is not.
Now the style combobox in examples/widgets/richtext/textedit can set
list item type, heading type or "standard" formatting, and also shows the
current formatting of the line that has the cursor. It was always a
shortcoming in this example that it only allowed setting the current line's

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.

It should be easier to translate sizes in bytes to human-readable
strings consistently rather than having to repeat this code (and the
string translations) in various places. The FileDialog in QtQuick.Controls
has a use for this, too.
[ChangeLog][QtCore][QLocale] Added QLocale::formattedDataSize() for
formatting quantities of bytes as kB, MB, GB etc.

There is no visible cursor on iOS, so updating the image is a waste
of time. Removing this does in fact speed up rendering of the strokes.
