accf7ce024 macOS: Disable explicit layerContentsPlacement
It was needed to allow lazy resize of the backingstore IOSurfaces, but
that feature hasn't been enabled yet, and explicitly setting the layer's
contents placement to NSViewLayerContentsPlacementTopLeft resulted in
the layer animating when the window was moved from screens of different
scale factors.

We need to investigate this further, but in the meantime fix the
visual regression by disabling the explicit layer contents placement.

e5f0fec762 Fix disabling AUTOMOC and AUTOUIC for generated resource cpp files
when using qt5_add_big_resources.

The previous approach of just setting SKIP_AUTOMOC and SKIP_AUTOUIC
on the generated source files is not enough because if AUTOMOC is
globally enabled, AUTOMOC will still run for the
rcc_object_{outfilename} target, which ends up creating a
mos_compilation.cpp.o file and adding it as a target object to the
target.

Thus later when $<TARGET_OBJECTS:rcc_object_${outfilename}> is passed
to the rcc invocation, the expression evaluates to a list of two
files: the rcc-related .o file and the mocs_compilation.o file.
Obviously that breaks the rcc invocation.

The fix is to disable AUTOMOC and AUTOUIC on the whole target, instead
of just the source files. This prevents the creation of the
mocs_compilation.cpp file.

a65800cc68 Add a clarification about "characters" to QTextCursor docs
The function name QTextCursor::positionInBlock() may give users the
idea that it can be displayed to the user as the visual position of
the cursor in the current block. This becomes confusing with some
writing systems, since e.g. a surrogate pair will count as two
characters while only representing a single visual grapheme.

Since it is an side effect of the encoding that will be unexpected to
many, and since it also touches on some linguistic complexities, we
add a note to the documentation to make users aware of the
consideration needed.

So rather than testing for non-zero doubles less than the smallest
float, test for non-zero doubles that cast to float zero; these
underflow.  This means small values close below the smallest float
shall round up to it, rather than down to zero, requiring a tweak to
an existing test.  Added a test for the boundary case (and tidied the

Corrected a lie in QTime()'s default constructor doc; it does not work

3b7db8ac90 Fix assert/crash when creating QBrush with null QGradient
The QBrush constructor taking a QGradient would assert or crash if
passed a null (NoGradient) gradient. But it is not necessary for the
API to be as brittle as that: instead the result can simply be a null
QBrush object, i.e. the same as the default QBrush() constructor
creates (style == NoBrush).

This issue comes up now since with the recent introduction of
QGradient presets, the API opens for using QGradient directly, whereas
earlier, only the subclasses QLinearGradient etc. were to be used.

69beb5f5a0 wasm: add resizeCanvasElement() API to qtloader.js
HTMl does not have per-element resize events, which
means Qt has not way of knowing that a canvas has been
resized and that the canvas buffer size should be updated.

Depending on the use case, the hosting JavaScript code
that caused the canvas resize could also inform Qt
that the canvas has been resized. Add API to do this,
which calls the existing canvas/screen resize implementation.

Other solutions taken/not taken:

- browser window resize events: these are available,
and we install an event handler in qwasmeventtranslator.cpp.

- DOM mutation events: would detect changes to the
the size attributes themselves, but not if the size
indirectly changed, e.g. “width: 100%” depends on the
parent width. Not implemented.

regression for OpenGL content from QOpenGLWidgets with WA_StacksOnTop

switching them to premultiplied (in case the - unrelated - raster
content has a _Premultiplied QImage format) breaks all content that

b82b3f4067 Fix the skip-check in TestMethods::invokeTest()
TestMethods::invokeTest() has an outer loop on global data (albeit
with a comment that said otherwise). On its first cycle, we run the
test function's *_data() method, if it has one; there is an inner loop
on the rows this created. If the *_data() QSKIP()s, we need to skip
the whole test; otherwise, a QSKIP() in one sub-test should not lead
to skipping the remaining sub-tests.

Moved the check for *_data() QSKIP()ping to right after *_data()
returns, inside the "first global cycle" block that runs it.
Previously, this check was done before entering the loop on local data
rows, but outside that "first global cycle" block: consequently, later
global cycles would fall foul of this check (even though the *_data()
hasn't been run in this cycle, much less QSKIP()ped in it) if the last
sub-test of the previous global cycle had QSKIP()ped.

When running a single test for one specific data row, if the test's
*_data() QSKIP()ped, this misplaced check would also have lead to a
misleading "Unknown testdata" warning.

Changed testlib/selftests' tst_globaldata::skipSingle() to trigger the
bug (by having its last local row of first global row skip, which
caused the second global row to be omitted) to verify this is also
fixed; and amended one of its comments to reflect what's now to be
expected. Updated the test's expected output files.

993b049adf Get rid of the locking in activate()
Removing connections and resizing the signal vector now
happens in a way that will not interfere with activate(),
as the old objects won't get deleted if we are somewhere
inside a signal emission.

This means that we don't need to lock the senders mutex
in activate anymore, as long as the reference counting
on the ConnectionData is atomic and we are in the senders
thread.

This implies that we now need to lock the receivers mutex in
queued_activate() abd blocking queued activation to ensure
it hasn't been deleted while we are emitting.

In addition, some precautions need to be taken to not read
from the receiver without holding the lock, as it could get
deleted while we're activating (if it's in a different thread).
To make that possible store the receivers thread id in the
connection data.

Use atomic pointers for all variables that can get modified
with the signalSlotLock() held and that are being read
without the lock being held.

This gives us a very nice additional speed improvement
for signal emissions.
