07d900dd57 rhi: gl: Make resolve on par with other backends
Just handling attachments with a render buffer set and only one
attachment is not what other backends do. They support all attachments
and also the cases of multisample (2D) textures and multisample texture
arrays.

By extension this allows multisample 2D texture arrays. (GL 3.2+/GLES
3.1+) This was previously not working probably since the correct texture
target was never used.

21f3a6d8c5 macOS: Propagate mouse enter/exit for windows embedded into foreign windows
Similar to the isEmbedded() case, when the parent of a QWindow is a
foreign window, created via QWindow::fromWinId(), we don't have a
QNSView parent that will handle mouse enter/exit on our behalf.

Longer term we probably want to fold this case into the isEmbedded()
case, but as that function is used other places too this requires
some more research, so for now let's fix hover events.

491534006e Fix disabled and inactive group palettes for windows native style
The dark mode related changes for windows didn't update disabled and
inactive group palettes, and this makes text in certain context
(such as menu bar) appear with enabled color. The windows theme API
populateLightSystemPalette() is responsible for this and it updates
palettes for color roles and certain inactive scenarios but not for
disabled.

This patch set makes existing systemPalette(Qt::ColorScheme) to be
available in QWindowsTheme and it updates palette depending on color
scheme. From now on, this API updates palettes for windows native
style. Its to be noted that window native style use light palette
irrespective of color scheme.

842cfcec80 QObject: introduce QT_NO_CONTEXTLESS_CONNECT
The 3-arguments overload of connect() is error-prone / easy to misuse:

* it's easy to e.g. connect to a lambda, and capture local state in the
  lambda. By not passing a receiver/context, the connection won't get
  disconnected if the local state gets destroyed (effectively, it
  creates a "dangling connection");

* in a multithread scenario, one may not realize that the connection is
  forced to be direct. If the signal is emitted in another thread than
  the one establishing the connection¹, then the functor will be invoked
  in that other thread. (Not that "the thread establishing the
  connection" has ever mattered, but again, this API is error-prone.)

Add a macro that allows users to disable the overload in their project.
I'm not going for deprecation because there's simply too much code
around that uses it.

[ChangeLog][QtCore][QObject] Added the QT_NO_CONTEXTLESS_CONNECT macro.
Defining the macro before including any Qt header will disable
the overload of QObject::connect that does not take a receiver/context
argument.

838fc606c1 Windows QPA: introduce a way to disable redirection surface
Why do we need this feature: to give user the possibility to explore
different interesting graphics features (currently only compatible
with D3D with the new FLIP model).

Why do we need to modify QPA directly: touch this flag after the
window has been created has no effect. It can only be used when we
call CreateWindow(), so we can't add this flag through SetWindowLong().
However, Qt doesn't provide any public or private interface to
control how Qt call CreateWindow(), and providing such interface
is also dangerous. Using environment variable to control this behavior
is the simplest solution and is commonly used inside Qt code base.

2a1772a649 QHeaderView: Don't add new sections on no-op
When a table view adds its first row, QHeaderView::initializeSections()
is called. It initializes the vertical header view with the number of
added sections. Subsequently QHeaderView::sectionsInserted() is called
with the same amount of newly added rows/sections.
That leads to the initial amount of sections being 2x the number of
rows added in the first go. In other words, the table view will display
at least one row more than the underlying table model has.

This patch adds an OR condition to the early return check at the
beginning of QHeaderView::sectionsInserted(). The method returns early
if the number of sections equals the number of respective sections
(rows in this case) in the model.

An autotest is added in tst_QTableView::rowsInVerticalHeader().

a0bcad3903 QAbstractProxyModel: delay headerDataChanged emissions when inserting/removing rows/columns
33c88f86b5 added some logic to QAPM in
order to have it automatically emit headerDataChanged when rows/columns
were added or removed in the model. This was done as a stopgap measure
to prevent QAPM from asking for illegal indices in order to implement
automatic remapping of the section headings (since there's no
mapSectionToSource).

The commit seems to have introduced a regression in QHeaderView, which
isn't prepared to receive headerDataChanged while a row/column count
change is in progress. When receiving headerDataChanged, QHeaderView
will try to read the row/column count and will store it internally.
When it will then receive the signals for insertion/removal of
rows/columns, it will interpret it as a modification of the previously
stored value -- even if the value it stored was already correct.

Fix this by avoiding to have two signals in flight at the same time;
emit headerDataChanged as a queued invocation.

551cbc5b15 iOS plugin: Make sure window is of type QUIWindow when determining the color scheme
In the iOS theme, we determine the color scheme based on the the last
UIWindow of the application, but listen to trait changes in the
QUIWindow class. However, the last window of the application is not
always a QUIWindow. Sometimes it can be a temporary UIWindow created
by the system for transitioning or other effects. These kind of windows
do not always follow the appearance of the app and the main window
(QUIWindow), so we were sometimes ending up with the wrong color scheme being reported.

This was happening when the app was put into background for example,
which causes the traitCollectionDidChange method to be called and query
the userInterfaceStyle of the last window to determine if the color scheme was changed. The queried window would sometimes end up being of type UITextEffectsWindow, etc. and report the wrong appearance.
To fix, always make sure to get the appearance from a QUIWindow.

5a6f51a322 rhi: d3d12: Use IDxcCompiler for SM 6.0+
Only when available at build time (dxcapi.h) and at run time
(dxcompiler.dll, ideally with dxil.dll).

The catch is that the latter will not be true in a typical Windows
system. Unlike the legacy d3dcompiler_47.dll the dxc stuff is just
not there. It is unclear what we can do about it. In the meantime
one needs to go to https://github.com/microsoft/DirectXShaderCompiler/releases
and get the DLLs.

b7d9b7fa69 rhi: d3d12: Implement multiview support
This relies on qsb being able to invoke dxc instead of fxc when the
request HLSL (shader model) version is 6.1.  (6.1 is required for
SV_ViewID) This currently works only when conditioning offline with
qsb (or via CMake), because qsb can easily invoke dxc instead of
fxc. When shipping HLSL inside the .qsb package (so when -c is not
specified or running the external tool fails), this won't work since
the D3D12 backend still uses D3DCompile(), not IDxcCompiler. Support
for that will be investigated separately.

We also need to bump to ID3D12Device2 and ID3D12GraphicsCommandList1.
With Windows 10 version 1703 being quite old now, this should not be a
problem at run time.

There are however issues at build time, namely that MinGW and
MinGW/LLVM and similar seems to have ancient Windows SDK headers
according to the CI test runs. None of the MSVC configurations have
this in the CI, they have reasonable versions of d3d12.h and similar.

Therefore, one important aspect of this change is that the D3D12
backend of QRhi will only be available from now on when the SDK
headers are new enough (meaning ID3D12Device2 is declared, which is a
several years old type now). Otherwise, QRhi::create() will simply
fail when asking for D3D12 with a helpful warning message about the Qt
build being crippled.

Implementation-wise, there are surprises in store as well:

The way the PSO is created needs to be revamped to follow the
extensible approach that uses a pipeline state stream
description. Both the graphics and compute pipeline creation is
changed to use CreatePipelineState() and the associated
machinery. This is only really essential for graphics pipelines since
we know have to include data for view instancing (multiview). For
compute the result is the same as before.

Additionally, the view count must now be baked into the
QRhiGraphicsPipeline. This means that applications must call
setMultiViewCount() with the same value (typically 2) *both* on the
render target's color attachment and on the pipeline. Backends that do
not care about the pipeline's view count (GL, Vulkan) will of course
ignore it, but if it's not set correctly D3D12 will fail. The manual
test is updated accordingly.

2b9ef2eb44 Pacify MSVC compiler incorrectly warning about unused variable
Under some circumstances, MSVC seems to complain about SlotArgumentCount
being unused

  qobject.h(210): warning C4189: 'SlotArgumentCount': local variable is
  initialized but not referenced
  note: see reference to function template instantiation
  'QMetaObject::Connection QObject::connect<void(__cdecl QAction::* )(bool),
  main::<lambda_1>>(const QAction *,Func1,
    const QtPrivate::ContextTypeForFunctor<main::<lambda_1>,void>::ContextType *,
    Func2 &&,Qt::ConnectionType)' being compiled

This is nonsense, as SlotArgumentCount is used in the next line, to
construct the list of signal arguments, but the workaround to declare
the variable as [[maybe_unused]] is trivial.

Add a connect statement to the test case that creates such a connection.
This does not produce any warning with or without the attribute (and if
it did, the build would fail for CI configuratinos setting -Werror).
