Changed signals and slots to new syntax, used nullptr and replaced
foreach with new C++11 range based for loops.
Also fixed a few minor flaws.

29af390e3f Clean up some arithmetic code in an example
The square root of a sum of squares is easier to read and should be
computed more accurately if done for us by hypot().  Variables set
only once should be set as an initializer and declared const, to make
clear this is what's happening.  Loop variables can be local to loops.
Adding a value to, or subtracting one from, a multiple of itself just
multiplies it be one plus (or minus) the multiplier; assigning the
result to the same variable is clearer as a *= (especially when the
factors are now overt numeric constants).  An array of 16k floats all
updated in locksteck to the same value can be replaced by a single
float that holds that value.  Simple things should not be needlessly
made more complicated - especially in example code, which should be
pedagogic.

8095c33bcd Use qRadiansToDegrees() and qDegreesToRadians() more widely
Especially in examples, where we should show off our convenience
functions, prefer calling these functions over doing arithmetic with
M_PI (or approximations thereto) and 180 (give or take simple
factors).  This incidentally documents what's going on, just by the
name of the function used (and reveals at least one place where
variables were misnamed; the return from atan is in radians, *not*
degrees).

Documentation does not match the sample code. There is no explicit
call to QWindow::create(). It is called implicitly by QWindow::show().

Furthermore, QWindow::create() documentation states: "Note that it is
not usually necessary to call this function directly, as it will be
implicitly called by show(), setVisible(), and other functions that
require access to the platform resources.".

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.

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.

formatting quantities of bytes as kB, MB, GB etc.

3e0bf04d7b Typo-fix: s/looses/loses/g
When an archer lets go of the bow-string, she looses an arrow; when
the hounds are straining at their leashes and the handler lets go, he
looses the dogs.  It's archaic usage now; we'd normally say "lets
loose", "lets go" or "releases".  In any case what was meant here was
that something got lost; a widget loses focus or a network loses its
connection.

If the respective modules aren't available we cannot build the tests
and examples. We drop the qtConfig(opengl) requirement for the opengl
examples as
a, we would need to make the QtGui configuration available for that to
   work, and
b, we should not add too much detail to the tests and examples build
   configurations. Checking each test and example for every feature it
   uses would be too much.

A convenience subclass of QWindow that provides a Vulkan-capable

Add also three examples of increasing complexity, and a variant that

the line's length is zero.

6aaf853222 make TabletMove hover events conditional on QWidget::tabletTracking
This adds the tabletTracking property in the same way that mouseTracking already
existed: there is a WA_TabletTracking attribute, and a TabletTrackingChange event
to notify when it changes.  So for widget applications it's an opt-in feature.
QtQuick applications don't yet make use of tablet events, but when they do
in the future, we don't yet have a mechanism to turn the move events off;
it remains to be seen whether that will be necessary.

[ChangeLog][QtWidget] QWidget now has a tabletTracking property, analogous
to mouseTracking, which will enable TabletMove events while the stylus is
hovering, even if no button is pressed.  This allows applications to show
feedback based on the other tablet event properties such as rotation and tilt.
