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.

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

variables were misnamed; the return from atan is in radians, *not*

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

This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for

use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.

{private,public}Feature to every referenced already existing entry.

As of version 10.12 (Sierra), the name of Apple's desktop operating
system will be macOS. Change the occurrences where the Mac platform
is discussed to use a macro \macos, which expands to 'macOS'. This
helps with adapting to future renaming.
Update the instructions on mac-specific Q_OS_* macro usage.
Add a \target for the old 'Qt for OS X' topic to keep links working
for other documentation modules that try to link with the old name.

This is only when the attached MIME data contains text, and we
fall back to rendering that text into a pixmap. It requires
getting the device pixel ratio from the source which, for now,
may be a QWidget or a QWindow. Other cases may exist, but that
would bring more dependencies than desired.
Similarly, it fixes the draggabletext example. Other examples
would require either to get updated pixmaps or change substantially
in order to support HiDPI (e.g., the fridgemagnets example).
