The existing get<I>() implementations are very clever™, if I, as their
inventor in at least the Qt ecosystem, may say so myself. E.g. the ()
around the return value are absolutely required, to ensure we return
by reference, not by value, through decltype(auto).
C++23 gives us forward_like, which doesn't require the parentheses,
because it always returns a reference.
Also replace decay_t with C++20's remove_cvref_t, the latter being
more efficient (performs less work).

along the x or y axis, some areas of the screen may move above the

The deprecation note for one of the operator* is wrong: Using
mapVector() is never the right choice given the deprecated operator*
itself is implemented by calling map(). It could be that in some cases
the results are identical so one can get away with migrating to
mapVector(), but this is incorrect in other cases and causes
regressions all over the place. Thus we should only recommend using
map() instead, never mapVector(). As shown by recent experiences, the
current docs are insufficient/wrong and caused a number of regressions
in the Qt code base as well.
Also enhance some related docs. It could be that the wording is not
always academically correct, however having some additional notes in
there help make it obvious to the reader (or at least raise some
alarms) that there are important differences between map and
mapVector.
Also improve the note for the other deprecated operator*. There is
only one way to convert to a vec4, given the existing implementation
of the operator, and that is by using 1 for w. Make this clear to the
reader.

This is heavily inspired by the patch written by Inho Lee
<inho.lee@qt.io>, which says "There is a precision problem in the
previous algorithm when checking pitch value. (In the case that the
rotation on the X-axis makes Gimbal lock.)"
In order to work around the precision problem, this patch does:
1. switch to the algorithm described in the inline comment to make
the story simple.
2. forcibly normalize the {x, y, z, w} components to eliminate
fractional errors.
3. set threshold to avoid hidden division by cos(pitch) =~ 0.
From my testing which compares dot product of the original quaternion
and the one recreated from Euler angles, calculation within float range
seems okay. (abs(normalize(q_orig) * normalize(q_roundtrip)) >= 0.99999)
Many thanks to Inho Lee for the original patch and discussion about
rounding errors.

The operation is sketchy for a number of reasons:
1) Mathematically, it doesn't make sense. The code interprets the
QVector3D as a point, extending it with w=1, and uses it as a
row vector. But similarly, the vector could be intepreted as a
directional vector, with w=0. No semantic is "better" than the
other.
2) QMatrix4x4 is not meant to be post-multiplied. Granted,
one could use a QMatrix4x4 as arbitrary storage for 16 floats,
but QMatrix4x4 builds itself to be always *pre* multiplied
(e.g. translate changes the 4th column, not the 4th row). We
can keep post multiplication for the general case if we do it
against a QVector4D, but I don't feel that we should support it
also for QVector3D.
[ChangeLog][QtGui][QMatrix4x4] The multiplication operator
(operator*) between a QVector3D and a QMatrix4x4 has been deprecated.

Use qHypot() to implement length(), avoid duplicating its code and use
its result more carefully, saving the need for casting to and from
double.
Subtracting a double from 1.0f still got a double, so the
qFuzzyIsNull() checks were using double's tolerance, where the use of
1.0f indicates the float tolerance would have been more apt. Also, use
qFuzzyCompare(_, 1.0f) instead of qFuzzyIsNull(_ - 1.0f).
In getEulerAngles(), scale co-ordinates by length before multiplying
(to ensure O(1) quantities) rather than scaling the products by the
squared length (possibly after {ov,und}erflowing).
