77389ad8ff macOS: Remove screen-update disable during resize
It was needed as a workaround for the window border and window content
becoming out of sync when we were drawing and flushing to the layer
from another thread using OpenGL. Since we've disabled ThreadedOpenGL
we can remove this workaround for now.

The workaround also had other problems, as windowWillResize: did not
turn out to be a reliable signal to know when a window was about to
resize. Since we override windowWillUseStandardFrame:, we would not
get the callback when zooming windows. Conversely, if we removed the
windowWillUseStandardFrame: override, we would get a single callback
for windowWillResize:, and then multiple callbacks that the window
had resized. In addition, windowWillResize: is not only used as a
callback, but also as a way to let the window delegate restrict the
size, so it's called when e.g. AppKit determines the standard frame
of the window -- an operation that doesn't involve an actual resize
operation.

If we re-introduce a workaround using screen-update disabling we need
a better hook than windowWillResize:, and we need to track when we
disable screen updates so that we can pair them up with corresponding
screen update enables, otherwise we'll get log messages in the console
about "SLSReenableUpdate: unbalanced enable/disable update".

6f9e444c28 harbuzzng: Remove assumption about Core Text working in 96 DPI
Core Text doesn't actually have a concept of DPI internally, as it
doesn't rasterize anything by itself, it just generates vector paths
that get passed along to Core Graphics.

In practice this means Core Text operates in the classical macOS
logical DPI of 72, with one typographic point corresponding to one
point in the Core Graphics coordinate system, which for a normal
bitmap context then corresponds to one pixel -- or two pixels for
a "retina" context with a 2x scale transform.

Scaling the font point sizes given to HarfBuzz to an assumed DPI
of 96 is problematic with this in mind, as fonts with optical
features such as 'trak' tables for tracking, or color glyphs,
will then base the metrics off of the wrong point size compared
to what the client asked for.

This in turn causes mismatches between the metrics of the shaped
text and the actual rasterization, which doesn't include the 72
to 96 DPI scaling.

If a 96 DPI is needed, such as on the Web, the scaling should be
done outside of HarfBuzz, allowing the client to keep the DPI of
the shaping in sync with the rasterization.

The recommended way to do that is by scaling the font point size,
not by applying a transform to the target Core Graphics context,
to let Core Text choose the right optical features of the target
point size, as described in WWDC 2015 session 804:

035d80407b Fix two smaller bugs in the BiDi engine
Remove wrong code changing the Bido level of line separators. This
lead to wrong ordering of the string in case the line separator was
meant to be ignored and the string should be rendered in one line. Line
breaks are anyways already reset to the paragraph level by the algorithm
and reordering is done on a line by line basis, so this will work
correctly when doing proper line breaking.

Secondly fix a small bug found while testing the above change, where
we wouldn't set the correct levels for boundary neutrals and explicit
embedding chars because we did that processing before we were fully
done with the BiDi algorithm.

c066656aff Avoid read-outside-array error by QStringRef over-reach
Constructing a QStringRef directly from the string, offset and a
length is UB if the offset + length exceeds the string's length.
Thanks to Robert Loehning and libFuzzer for finding this.
QString::midRef (as correctly used in both changed uses of QStringRef,
since 432d3b6962) takes care of that for us.  Changed one UB case and
a matching but correct case, for consistency.

In the process, deduplicate a QStringList look-up.
Added tests to exercise the code (but the one that exercises the
formerly UB case doesn't crash before the fix, so isn't very useful;
the invalid read is only outside the array it's scanning, not outside
allocated memory).

can be re-enabled now.

150c6fb74b Add testlib selftests for double and for non-finite float and double
Tidied up the existing float tests in the process.
(In particular, s/SUCCESS/PASS/ since that matches real test output.)
These verify that QCOMPARE() handles floats and doubles as intended.
Extended the existing qFuzzyCompare tests to probe the boundaries of
the ranges of values of both types, in the process.

Revised the toString<double> that qCompare() uses to give enough
precision to actually show some of the differences being tested there
(12 digits, to match what qFuzzyCompare tests, so as to show different
values rather than, e.g. 1e12 for both expected and actual) and to
give consistent results for infinities and NaN (MinGW had eccentric
versions for these, leading to different output from tests, which thus
failed); did the latter also for toString<float> and fixed stray zeros
in MinGW's exponents (which made a kludge in tst_selftest.cpp
redundant, so I removed that, too).

That's further complicated handling of floating-point types, so let's
just keep an eye on how expensive that's getting by adding a benchmark
test for QTest::toString().  Unfortunately, default settings only get
runs that take modest numbers of milliseconds (some as low as 40)
while increasing this with -minumumvalue 100 or more gets the process
killed - and I'm unable to find out who's doing the killing (it's not
QProcess::kill, ::kill or the QtTest WatchDog, as far as I can tell).
So results are rather noisy; the integral tests exhibit speed-ups by
factors up to 5, and slow-downs by factors up to 100, between runs
with and without this change, which does not affec the integral tests.
The relatively modest slow-downs and speed-ups in the floating point
tests thus seem likely to be happenstance rather than signal.

37352b23a9 x86: Disable AVX support on 64-bit MinGW
GCC for 64-bit Windows has a bug that it fails to properly re-align the
stack pointer for use with 256-bit memory addresses (AVX). Therefore,
there's about a 50/50 chance that any function using AVX will have an
improperly-aligned stack. In release mode, stack accesses should be
rare, but in debug mode they happen frequently. Either way, this is a
ticking time bomb, so we disable.

Clang is not affected.
32-bit MinGW is not affected.
64-bit in other OSes with GCC are not affected.

c66ddd7aba Include relevant example code in documentation of setUrlHandler
By only looking at the function prototype, it's tempting to assume that
the handler needs to be registered with the usual SLOT macro. That is
not the case.

The code snippet is already included in the class description, but it
doesn't hurt to repeat it here.

a2b8f891fa Doc: decrease confusion about HSV vs HSL in QColor
The non-qualified hue() and saturation() etc. refers to those values
in the HSV, not HSL, color model. Make this more explicit in the
documentation to avoid confusion.

01f090e9e4 Fix QColor::toCmyk() for rgb(0, 0, 0)
We translate all pure gray colors into cmyk having c,m,y=0 and only
the k value expressing the darkness. But a fix introduced to avoid
division by 0 caused rgb(0, 0, 0) to be an exception to this; it ended
up being translated as c,m,y,k=1 instead.

Fix by catching the potential div-by-0 situation earlier and directly
set the orthodox cmyk translation: c,m,y=0,k=1.

66c3a71e91 Painter path stroking: fix capping of beziers ending in tight turns
For some overly tight beziers where the start or end point and the
next control point are closer than the pen width, the stroker's
shifting algorithm will produce a start/end tangent pointing in the
opposite direction from what is expected, for one of the sides. This
would break the square and round capping logic. Fix by detecting the
situation in the capping function and reversing the tangent when
necessary.

e96641d881 Fix xbm image format handler: properly reject invalid files
The read_xbm_header() function is used to check for valid file header,
containing valid width and height values. But in case of an invalid file,
the check could depend on uninitialized variables.

0736e050cb QMenuItem: fix rendering with css styling
The rendering of a css styled menu item with icons or checkmark was
partially fixed with aa1bc47942 but
introduced some other painting regressions, especially in RTL mode.
Fix it by syncing the code with fusion and windows style. With this
patch a menu text with a check mark but no icon is now aligned exactly
the same as a menu text with a icon.

d726ccb83c tst_QHeaderView: fix defaultSectionSizeTest() on High-DPI screens
tst_QHeaderView::defaultSectionSizeTest() fails on High-DPI screens
because the default minimum section size is greater than the values used
for testing the header sizes. Therefore the test will fail.
Fix it by explicitly setting the minimum header size to something
smaller than the test values.
Also add a debug line to output the default minimum section sizes so
other failures due to this problem can be debugged better.
