8fa91c75ad Clean up code that handle clipboard image conversion on Windows
This commit remove old legacy code that try to deal with clipboard
image conversion in the qwindowsmime class. It now uses
qbmphandler under the hood which is much more complete.
It also add a small fix for the conversion
of BI_RGB clipboard image with an explicit alpha layer (which Firefox
use on Windows).

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
as well as https://bugs.kde.org/show_bug.cgi?id=411718

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.

qt_plugins target is needed by qt_internal_add_plugin function, but when
standalone building sqldrivers, this target does not exist, which causes

c30d05e794 macOS: Simplify and fix issues with QMenuPrivate::moveWidgetToPlatformItem
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.

74559dccc8 Update QPalette() documentation to not mention the application palette
It's an implementation detail that the default constructed palette
happens to use the d-pointer of the application palette, and as a
result has the same colors as the application palette if requested.

The palette has an empty resolve mask, and hence all the colors in
the palette are undefined. Users should not rely on QPalette() to
represent the application palette when for example overriding a
parent palette.

1b4d70676c CMake: Prefer canonical CMAKE_ANDROID_NDK var when writing deploy file
CMAKE_ANDROID_NDK is an official variable provided by CMake. The
ANDROID_NDK variable will be set by the NDK toolchain file, but we
don't need to rely on that (the user could theoretically not be using
the NDK's toolchain file). Using the CMake-provided variable means
we don't have to explain the source of the variable in documentation
for the qt6_android_generate_deployment_settings() command. We should
prefer to use things provided by CMake already where it makes sense
and this seems to be one such case.
