3fc6b45cbb QProcess/Win: move pipe draining into QWindowsPipeReader
... where it belongs.

To avoid the loop, introduce the drainAndStop() function, which allows
QWindowsPipeReader to flush the pipe itself. It determines the number of
bytes pending and blocks until the remainder of the process output is
received.

Note that the loop in drainOutputPipes() didn't actually have to
interleave the two pipes (because we're presuming that the operations
will finish instantly), so we don't do it now. Also, the code violated
the API contract: 'true' was returned when the 'wrong' channel received
data; this is now fixed as a side effect.

df0e98d408 rhi: Pipeline cache load/save
Add QRhi APIs to retrieve and reload the contents of the "pipeline
cache".

The only API where there is a true pipeline cache is object is Vulkan
(VkPipelineCache). For OpenGL, the other backend where we support this,
it is simulated with program binaries. The Qt 5 style OpenGL program
binary disk cache continues to work like before, but one has now the
option to do things in a more modern, graphics API agnostic way, that
leads to generating a single blob instead of a large set of files in
some system location, allowing easier "pre-baking" of the cache content.

It is expected that Qt Quick exposes the two new functions in form
if QSG_RHI_ environment variables, thus allowing easy testing and
cache file generation.

As an example for the performance improvements this can give, consider
Vulkan, where we do not have any existing persistent caching mechanism
in place:

Running BenchmarkDemoQt6.exe --scene flythrough --mode demo creates 18
QRhiGraphicsPipeline objects from Qt Quick and Qt Quick 3D.

The total time spent in QRhiGraphicsPipeline::create() during application
startup for these 18 pipelines is 35-40 ms on a given Windows (NVIDIA)
system.

When exporting the pipeline cache contents to a file, and then, in a
subsequent run, reloading the cache contents, this is reduced to 5-7 ms
on the same system, meaning we get a 6-7x improvement.

The generated data is always specific to a given Qt version, RHI
backend, graphics device, and driver version. Much of the implementation
consists of adding and verifying the appropriate header to the blobs
retrieved from the driver, to allow gracefully ignoring data that was
generated with a device or driver that differs from the one used at
run time. This should provide robustness, even if the Vulkan or OpenGL
implementation is for some reason not prepared to identity and reject
incompatible cache/program blobs.

3861ec735e QProperty: Add private isAnyBindingEvaluating function
To optimize certain operations, it can be useful to know whether we are
currently evaluating a binding. For instance, we have properties whose
storage is only alloctaed on-demand when they are set. However, we would
also allocate them if they are used in a binding context, as we would
otherwise not properly track the dependency. Using
isAnyBindingEvaluating in the getter, we can detect this
situation, and avoid the allocation if it returns false.

This API is private for now, as it exposes some internals of the
property system and should be used with care. As it needs to access the
TLS variable, it also has a non-negligible cost.

events. While support still exists for before 13.4 then both approaches

aa09bea00c control scrolling of QTabBar using StyleHint
Mouse wheel/touchpad scroll signals sent to the tab bar trigger
cycling through the tabs. In applications where the tab bar is
close to "mouse click hotspots", the cursor may accidentally be
left over the tab bar instead of the main content of the window.
When the user wants to scroll up/down the main conten, the
scroll signals are thus sent to the tab bar and instead of
scrolling, the focus switches to another tab. This is
confusing to the user, because not only does the application
not carry out the desired action (scrolling through the main
content), it jumps to a different tab. Two common examples of
applications affected by this nuisance are Konsole and any kind
of browser (file browser or web browser), where the address bar
is right below the tab bar. Moreover, on macOS, scroll events
do not have an effect on the tab bar widget of the native UI.
Currently, the code makes use of preprocessor directives to
achieve consistent behavior on macOS (`#ifndef Q_OS_MAC`). This
patch implements the check of a StyleHint in order to determine
if scroll events on the tabbar should have an effect. This
approach is more consistent with Qt coding style than
OS-dependent preprocessor directives and, in addition, makes
the behavior configurable according to the user's preferences.

[ChangeLog][QtWidgets][QStyle] Added
SH_TabBar_AllowWheelScrolling as a style hint to enable/disable
cycling through tabs using the scroll wheel. This defaults to
true in all styles except the macOS one so there is no change in
existing behavior.

c6d6029909 Update QVulkan(Device)Functions to Vulkan 1.2
This also needs improvements to qvkgen. What we get with this patch
are the Vulkan 1.1 and 1.2 core API's additional 11 instance-level
and 30 device-level commands present in QVulkanFunctions and
QVulkanDeviceFunctions.

All of these are attempted to be resolved upon construction. When the
implementation does not return a valid function pointer for some of them
(e.g. because it is a Vulkan 1.0 instance or physical device), calling
the corresponding wrapper functions will lead to unspecified behavior.
This is in line with how QOpenGLExtraFunctions works. The simple
autotest added to exercise some Vulkan 1.1 APIs demonstrates this in
action.

The member functions in the generated qvulkan(device)functions header
and source files are ifdefed by VK_VERSION_1_{0,1,2}. This is essential
because otherwise a Qt build made on a system with Vulkan 1.2
headers would cause compilation breaks in application build environments
with Vulkan 1.0/1.1 headers when including qvulkanfunctions.h (due to
missing the 1.1/1.2 types and constants, some of which are used in the
function prototypes). In practice this should be alright - the only
caveat to keep in mind is that the Qt builds meant to be distributed
to a wide variety of systems need to be made with a sufficiently new
version of the Vulkan headers installed, just to ensure that the
1.1 and 1.2 wrapper functions are compiled into the Qt libraries.

It used QString.compare() and assumed it was returning a bool true on
equality, when it actually returns an int that compares to 0 as the
given strings compare. So it should use compare() == 0.

This fixes several of QTimeZone's blacklisted tests on Android and a

50c63446f5 Fix problems with offset-derived ids for QTimeZone
When creating a time-zone from a UTC+offset name that isn't known to
the system, QTimeZone (since the fix to QTBUG-77738 in 5.15.0) falls
back to constructing a suitable UTC-offset backend; however, the id of
this is not guaranteed to match the id passed in to the constructor.
In all other cases, the id of a QTimeZone does match the id passed to
its constructor.

Some utcOffsetId testcases had different id() than the id passed to
the constructor, due to mismatches where a zone was constructed using
the fall-back but the generated id included its minutes (as :00) or
omitted its seconds. The omission of seconds is clearly a bug, but we
also don't want to include :00 for seconds when it's not needed. So
change QTimeZonePrivate::isoOffsetFormat() to accept a
QTimeZone::NameType to configure how much we include in an id. Its
callers other than the relevant constructor (from offset) still get
minutes, even when :00, but will also get seconds added if that isn't
zero; and the constructor from offset now gets the short form obtained
by omitting all trailing zeros.

Since all valid whole-hour offset names that do include :00 for the
minutes field are in fact known standard offset names, the elision of
minutes will only affect zones created by ID in the case of a
whole-hour offset given without :00 minutes specifier, so these shall
necessarily in fact get the ID passed to the constructor. Creating by
UTC-offset with a name that specifies zero seconds will result in a
QTimeZone instance whose id() differs from what was passed to its
constructor (eliding the :00 seconds and potentially also minutes, if
also zero) but this should be the only case where a QTimeZone's id
doesn't match the one passed to the constructor, when constructed by
id.

Fixed inconsistency between the offset-constructor's declaration
(taking offset as int) and definition (taking qint32) in the process.
Added an id check to the utcOffsetId() testcase. Amended two tests of
offset-derived time-zones' IDs, added comments to make clear how one
of those differs from a matching standard name test and converted two
uses of QCOMPARE(, true) to QVERIFY().

[ChangeLog][QtCore][QTimeZone] QTimeZone instances created by offset
from UTC (in seconds) shall now only include minutes in their ID when
the offset is not a whole number of hours. They shall also include the
seconds in their ID when the offset is not a whole number of minutes.

5a0e5521e4 QVectorND: make some constructors explicit
QVector2D has implicit conversions towards QVector3D/4D, and
QVector3D has an implicit conversion towards QVector4D. Although
in principle this is fine because it's not a data loss, it's still
sketchy; for instance, it allows mixed operations to compile:

  vector2d + vector3d;
  vector4d - vector3d;
  vector3d * vector4d; // !

(Random observation: the conversion from QPoint(F) to QVectorND are
actually already marked as explicit.)

This is a leftover not done for Qt 6.0. I am not making these opt-out:
having an implicit conversion here is outright *dangerous*, and any usage
that fails to compile needs to be inspected to make sure it was the
intended behavior.

[ChangeLog][Potentially Source-Incompatible Changes] The
QVector2D/3D/4D converting constructors from another QVectorND
now explicit. This was done to prevent a category of bugs resulting
from operations accidentally mixing QVectorND objects.

In Qt 6, we do not require Q_DECLARE_METATYPE before using fromValue,
and QMetaType itself works with non-copy constructible types just fine.
However, QVariant still requires it, thus we need to now enforce this in
fromValue itself.

b0add5bf2f QtEntryPoint: Fix linking Release against RelWithDebInfo with MSVC
To be able to link a Release user project against a RelWithDebInfo Qt we
set several IMPORTED_*_RELEASE properties in
the *AdditionalTargetInfo.cmake file of each Qt module.

The EntryPoint module however is a bit special as it is an
INTERFACE_LIBRARY linking publicly against a static
library (EntryPointimplementation). Its *AdditionalTargetInfo.cmake file
was almost empty, because qt_internal_export_additional_targets_file was
called before EntryPointImplementation was set up. Also,
qt_internal_add_module, which calls
qt_internal_export_additional_targets_file, does not know that we want
to export the EntryPointImplementation target.

We fix this by telling qt_internal_add_module(EntryPoint) to not
generate the *AdditionalTargetInfo.cmake file and call
qt_internal_export_additional_targets_file later to take the targets
EntryPoint and EntryPointImplementation into consideration.

qt_internal_add_module learned the option NO_ADDITIONAL_TARGET_INFO to
turn off the generation of *AdditionalTargetInfo.cmake files.

child widget that can hold the focus and call its setFocus() method,
which also updates focus widgets of all its parent wigets.

In case if the focus widget is the active window itself, we only set it
as the application's focus widget, but we don't update the focus widget
of the active window itself. Because of this the focusWidget() method
always results nullptr for the active window. This prevents from setting
the focus back to active window after the focus has changed (for example
after a context menu is closed, as in the bugreport).

257edbfa53 Prevent compiler and linker flags from growing every cmake run
Functions in QtFlagHandlingHelpers.cmake try to update the CMake cache
variables for compiler and linker flags. These were using the current
value of those variables and writing the modified ones back to the
cache every time CMake ran. If a toolchain file sets or modifies any of
these variables, that updated value is used and written back into the
cache instead of the original cache variable's value. The next time
CMake executes, the toolchain file re-applies the same change and the
variable grows longer each time with flags repeated. With Ninja, this
causes a complete rebuild every time CMake is re-run. The Android NDK
toolchain file is one example where this behavior is triggered (the
fault is shared, one could argue that the NDK should only be setting
..._INIT variables, but that's out of our control).

Another related bug in the previous implementation was that the flags
used to build after the first CMake execution could be different to
those used for all builds after the second and later CMake runs. This
is because the CMake cache was being updated, but not always the
calling scope of the functions that modified them. If a toolchain file
set any of the compiler or linker flag variables as non-cache
variables, then updating the cache variable would have no effect on
the calling scope. The non-cache variable would continue to take
precedence for that scope for that run. The next time CMake executes
though, the updated cache variable would now have been used by the
toolchain file and the change *will* be part of the non-cache
variable's value.

The above are examples of why you should try to avoid updating these
cache variables from project code. We could leave the cache alone and
always update only non-cache variables, but then a developer looking
at the cache may wonder why the values they see there don't match the
values being used in builds. Or worse, they think the cache values
are being used and don't realize the builds are using something
different. Ultimately, we have to choose which downside we are happy
to live with. The changes here preserve the previous intent of
updating the cache, but it's still a bit fragile.

00505ed2b5 Widgets: fix setTabOrder for QAbstractSpinBox-like widgets
setTabOrder was not considering the case, when a child widget has
its focus proxy set to its parent widget. This happens, for example,
for the QLineEdit that is nested inside the QAbstractSpinBox.
For such cases the lastFocusChild was calculated incorrectly, and, as
a result, such child widgets were not correctly positioned in the
focus chain. This could lead to an error while backtabbing.

Here is a brief example. Suppose we have 3 widgets arranged like this:

auto spinBoxOne = new QDoubleSpinBox;
auto spinBoxTwo = new QDoubleSpinBox;
auto button = new QPushButton;

Then the default widget focus order is:
- spinBoxOne
- lineedit (from spinBoxOne)
- spinBoxTwo
- lineedit (from spinBoxTwo)
- button

Before this commit setting the explicit tab order changed the focus
order in the following way:

QWidget::setTabOrder(spinBoxOne, spinBoxTwo);
QWidget::setTabOrder(spinBoxTwo, button);

- spinBoxOne
- spinBoxTwo
- button
- lineedit (from spinBoxOne)
- lineedit (from spinBoxTwo)

In this case, backtabbing from spinBoxOne actually leads us to
lineedit (from spinBoxTwo), which refers to spinBoxTwo.
And so we're stuck in a loop.

This commit fixes the issue by handling such special case, and
preserving correct focus order.

Note: the actual unit-test in this patch uses QLineEdit instead of
QPushButton, because one can't tab to buttons on macOS by default.
However the general idea is the same.

aeeac48cbd AA_SynthesizeTouchForUnhandledMouseEvents: keep correct coordinates
QGuiApplicationPrivate::processMouseEvent() sends a
QWindowSystemInterfacePrivate::TouchEvent if the mouse event is not
accepted and AA_SynthesizeTouchForUnhandledMouseEvents is enabled.
A QPA TouchEvent always contains native touch points, which is why
it calls QWindowSystemInterfacePrivate::fromNativeTouchPoints to
translate the QMouseEvent's device-independent position back to the
raw position that it would have had if it came from a real touchscreen.
Therefore we must give that function touchpoints that are actually in
native coordinates.

It may be that some of this transformation could be avoided entirely,
but here we prove that the existing way works correctly, by adding
coordinate checking to the tst_QWindow::mouseToTouchTranslation() test.

583668005d a11y: Do not cache classes that don't have a factory plugin
For Qt Widgets we thought it was a good idea to also store in the cache
if a class didn't have a factory plugin. This worked fine there, since
the number of QWidget classnames is quite limited (so the factory plugin
cache will soon reach a limit)

In QML however, classes are often suffixed with e.g. Button_QMLTYPE_123,
Button_QMLTYPE_124 etc.
This number suffix is just increased continuously. This could lead to that
the factory plugin cache will grow ad infinitum, which will cause
"memory leaks" in addition to a performance penalty.

c262a69851 rhi: gl: Add some enablers for supporting GL_TEXTURE_EXTERNAL_OES
From QRhi's perspective this consists of two things:

- A shader with samplerExternalOES in it cannot go through the standard
  pipeline. Rather, a QShader with suitable GLSL code in it has to be
  constructed manually. As this is something useful as an autotest
  anyway, add a test case to the qshader autotest that demonstrates
  this.

- When it comes to correctly calling glBindTexture, add a QRhiTexture
  flag. The expectation is that an OpenGL-only client sets this in
  combination with QRhiTexture::createFrom(), thus wrapping an existing
  texture that then gets bound to the GL_TEXTURE_EXTERNAL_OES target
  instead of our usual GL_TEXTURE_2D.

For completeness we also add a SamplerExternalOES variable type to
QShaderDescription, but the sampler type is not actually used by the
QRhi OpenGL backend, as it is the QRhiTexture that defines the
texture target.

376e3bd8ec Introduce QUrlResourceProvider to load resources for HTML
QTextDocument and the text editor classes suggest to override
their loadResource() methods to provide data associated with
a text document. This approach has the following drawbacks:
- it requires subclassing
- there is no way to set a global resource provider
- QLabel is missing virtual loadResource() method and
  it can't be added without breaking ABI

QUrlResourceProvider is designed to solve these issues.
One should create a derived class that implements
QUrlResourceProvider::resource(). The objects of the derived
class then can be set for any text document.
The default resource provider can be set with
QUrlResourceProvider::setDefaultProvider().
This change also adds QLabel::setResourceProvider(),
which doesn't break ABI.

[ChangeLog][QtGui][Text] Introduced QUrlResourceProvider that allows to
load resources for HTML. It is intended to replace the use of
QTextDocument::loadResource().

6a3f8cbc3a Use design metrics when adding text to QPainterPath
When we add text to QPainterPath, we will add the design metrics
(unhinted glyphs) and scale these down to match the target font size.
But the glyph positions we pass in are based on the hinted metrics,
samples at the target font size. Thus, on fonts/systems with hinting,
these do not match the scaled design metrics outlines.

a75bdfda3d Clarify variable names in QPropertyObserverPointer::notify
In QPropertyObserverPointer::notify and its calling sites,
variable names "alreadyKnownToHaveChanged",
"knownIfPropertyChanged", "propertyChanged", and at its calling site
"knownIfChanged" are used. This is confusing. This patch
changes those four to "knownToHaveChanged". For the logic
implemented it is not necessary to track whether we
have knowledge about having changed and whether it has
actually changed (if we have knowledge) separately.

6a6d12ea4b Split QProcessPrivate::_q_processDied()
The completion of the child process can take place asynchronously or in
one of the waitFor...() functions. In both cases, we used the same
handler (_q_processDied()), which caused several problems:

  a. technically, waitForReadyRead() should have taken into account the
     result of the calls to _q_canRead...() slots inside the
     _q_processDied() function:

       - the user calls waitForReadyRead();
       - forkfd descriptor becomes signaled, while a grandchild
         process is still alive;
       - as readyRead() signal has not been emitted, _q_processDied()
         is called;
       - the grandchild process writes to stdout pipe;
       - now data arrives, and _q_processDied() will collect it, but
         won't report it.

  b. we had a bug with recursions on Unix:

       - death notification comes asynchronously;
       - waitForDeadChild() closes forkfd;
       - _q_canRead...() emits readyRead();
       - a slot connected to readyRead() calls waitForFinished();
       - waitForFinished() hangs (forkfd == -1).

   c. for blocking functions, drainOutputPipes() was called twice on
      Windows.

By introducing a new processFinished() function, we leave the read
operations in the _q_processDied() slot, while the process completion
code is guaranteed to run only once.

423e6c3635 QProcess/Unix: consolidate process state tracking socket notifiers
There is no reason to have the startup notifier and the death notifier
be active at the same time, as the former will detect death as well.

Previously, these notifiers were racing, but _q_processDied() ordered
signals by calling _q_startupNotification() manually. Thus, the
started()/finished() sequence was always emitted if the child process
was killed anywhere. Now this ordering is simply not necessary anymore.

This makes it possible to reuse the startup notifier for death
notification.

e7370d0583 Skip already closing widgets when checking whether application can quit
QApplication tries to close all windows on quit using closeAllWindows,
but closeAllWindows skips windows that are already closing. This can
happen when calling quit() from a close event for example.

QApplication then tries to verify that all windows have been closed,
and that logic should skip the same kind of windows as closeAllWindows
does.

The fact that these two logics diverge was identified earlier in
5af73cd9db, but aligning them required further work. As that
commit notes, the right fix to align them is building on top of
tryCloseAllWidgetWindows(), which already returns true/false based on
whether it could close all windows or not. But, unlike the existing
logic in QApplication::event(), it doesn't skip Popups or Dialogs,
so that discrepancy needs further research.

3ce5128d80 Fix missing repaints with QOpenGLWidget in a QDockWidget
When AA_ShareOpenGLContexts is not set, docking or undocking
will lead to changing the associated top-level window. This
leads to changing the OpenGL context, and tearing down and
then recreating all OpenGL resources (assuming a well written
application). The problem is, there are no paint events after
the Show, meaning the user code's paintGL is often not invoked,
which leads to showing an empty QOpenGLWidget until something
else triggers a paint event. To remedy this, send a paint event
upon Show, which should be harmless enough, while fixing the
case of docking/undocking.

5f8efb2597 rhi: gl: Reset tracked state upon a buffer update or readback
...encountered in the command list.

Move all, previously local, tracking variables into a struct. This
allows creating helper functions to reduce error-prone repetition in the
executeCommandBuffer() function body.

The only real change in the patch is in the handling of
Command::BufferSubData and Command::GetBufferSubData: here, instead of
calling glBindBuffer directly, use a helper function that also resets
the relevant state tracking variables. A subsequent
Command::BindVertexBuffer or BindIndexBuffer will therefore correctly
rebind the appropriate buffers.

This is particularly relevant with certain command stream patterns
exercised by some Qt Quick 3D scenes:

- A View3D renders a mesh,
- another View3D has some 2D Qt Quick content, as well as a model with
  the same mesh.

When both View3Ds use the default Offscreen render mode, the resulting
command list consists of segments along the lines of:

1. prepare resources for first View3D

2. render content for first View3D - this binds the vertex and index
   buffers for the mesh (state is tracked; all 1-4 steps are within
   the same command list, processed by a single call to
   executeCommandBuffer())

3. prepare the content for the "inline" 2D Qt Quick scene - this may
   update vertex and index buffers, that may lead to adding
   BufferSubData commands to the list (tracked state (last
   vertex/index buffer) may need invalidation/updating - and that's
   where our problem lies)

4. the second View3Ds 3D content is rendered: a model with the same
   mesh as the last (Quick)3D draw call, so same vertex and index
   buffers. If #3 did not invalidate and/or update the tracked state,
   the glBindBuffer calls are (incorrectly) skipped.

0cbbba2aa5 Update shared-mime-info to the 2.1 release, adjust implementation
The spec hasn't changed, but I made the same mistake in xdgmime
(the reference implementation) and in Qt: when multiple globs match,
and the result from magic sniffing is unrelated to any of those globs,
then I used the magic result, but that's wrong, globs have priority
and one of them should be picked up.

This is now fixed in xdgmime
(https://gitlab.freedesktop.org/xdg/xdgmime/-/merge_requests/3)
and in the expected results in shared-mime-info
(https://gitlab.freedesktop.org/xdg/shared-mime-info/-/merge_requests/99)
which this commit is also tested against.

This change also optimizes QMimeBinaryProvider::addFileNameMatches
to have the same logic as xdgmime for glob matching:
literals > extensions > other globs
As soon as one category matches, we can stop there.
This makes no difference in the overall results, in practice.

The user bug report (against the Qt implementation, actually)
is https://gitlab.freedesktop.org/xdg/shared-mime-info/-/issues/138

587fed817a Add a platform capability indicating support for QRhi-based rendering
This attempts to reconcile a minor difference between Qt 5 and Qt 6:

Running Qt Quick applications with a platform plugin such as vnc,
led to an automatic fallback to the 'software' backend based on
the OpenGL capability reported from the platform plugin. In Qt 6.0
this logic is gone from Qt Quick, because we do not have, and wish
not to have, individual flags for each and every 3D API on this
level.

Therefore in Qt 6.0 a Qt Quick application running with the vnc
(or linuxfb, or minimal) platform needs an explicit selection of
the software backend via QT_QUICK_BACKEND or
QQuickWindow::setGraphicsApi().

To keep migration for users of such platform plugins easier, we
can still reintroduce a Qt 5-like logic: by having a high level
Is-QRhi-Supported type of flag, we can make Qt Quick query that,
and trigger the fallback to the software backend when it is
reported as false by the platform plugin. As this is the minority
case and a conscious choice by platform plugins, the flag can be
opt-out (i.e. true by the default hasCapability implementation).

When it comes to the existing OpenGL flag, that needs to stay for
compatibility reasons, but it is worth noting that the new flag
semantically falls in the exact same category: it does not indicate
things will really work at run time, but rather serves as an opt-out,
"do not even try" type of declaration the platform plugin can make,
which then allows modules like Qt Quick to make early, upfront
decisions about which rendering paths/backends to take.

97da4519ba Add a dedicated QWindow surface type for D3D
Even though there is no D3D-specific logic in the windows platform
plugin, meaning a QWindow with either OpenGLSurface or VulkanSurface
(or anything really) is DXGI/D3D-compatible, it now looks like it is
beneficial, and more future proof, if there is a dedicated surface
type.

As the linked report shows, there are OpenGL-specific workarounds
accumulated in the platform plugin, while not being clear if these
are relevant to non-OpenGL content, or if they are relevant at all
still. (and some of these can be difficult/impossible to retest and
verify in practice)

When D3D-based windows use the same surface type, all these are
active for those windows as well, while Vulkan-based windows have
their own type and so some of these old workarounds are not active
for those. To reduce confusion, having a dedicated surface type for
D3D as well allows the logic to skip the old OpenGL workarounds,
giving us (and users) a more clear overall behavior when it comes
to OpenGL vs. Vulkan vs. D3D.

The change is compatible with any existing code in other modules
because any code that uses OpenGLSurface for D3D will continue to
work, using the new type can be introduced incrementally.

View embedding when QWidget is involved is a bit finicky. This change
breaks down the steps needed to embed it into an NSMenu item, and
simplifies the process by not relying on a container widget.

The main issue is that QCocoaWindow::recreateWindowIfNeeded() will
potentially create an NSWindow for the embedded view, resulting in
a stray view. To prevent this we set the Qt::SubWindow flag on the
window, but QWidget tends to reset this flag when the widget doesn't
have a parent, so we need to be careful about which order we do the
setup.

162a859045 Add getDataView() method to QTextureFileData
This method will return a QByteArrayView of the data range corresponding
to the level. This avoids a leaky abstraction by moving the needed data
pointer arithmetic from the caller to the method. It will also make it
easier adding cubemap support in the future.

824c726340 QRegularExpression: mention raw string literal in the docs
Raw string literals (since C++11 according to [1]), make writing/reading
regex patterns easier, since one can just use e.g. "\w\d" without having
to escape those backslashes e.g. "\\w\\d"; this is especially useful with
longer/more complex regex patterns.

c80d6473fb Fix out-of-bounds write
Change ac210c73e4 introduced the requirement that all input devices with
Scroll capability must have a QXcbScrollingDevicePrivate as their d_ptr.
However, this was not enforced, and would fail for the "Virtual core
pointer".

To fix this, always use qobject_cast to verify that the device is of the
correct type.
