The resize event should not be used to draw, as there will be a follow-up

This is how QRasterWindow operates too, except it defers the backingstore

It's also how QOpenGLWindow operates, which also has a note for the

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
block format but had no feedback to show the current format.

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
name of the function used (and reveals at least one place where
variables were misnamed; the return from atan is in radians, *not*
degrees).

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.

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.
