f3e27d3688 Pick up initial state of foreign windows instead of reflecting QWindow
A foreign window can be used both for embedding a Qt window into a
native window hierarchy, or for embedding a native window into a Qt
window hierarchy. In the former case, we should not modify the foreign
window in any way. Since the platform does not know anything about the
intended use case at the time of the foreign window creation, it should
avoid modifying the foreign window in any way, and should instead pick
up the foreign window state and reflect that through QWindow.

9a39b3c796 Apply ScaleFactorRoundingPolicy to QT_SCREEN_SCALE_FACTORS
QT_SCREEN_SCALE_FACTORS is in many cases set on behalf of the user,
instead of by the user, so we should apply the standard app
scale factor policies to it, instead of interpreting it
as a user override.

Specifically, make it subject to the rounding policy set by
QGuiApplication::setHighDpiScaleFactorRoundingPolicy(). This
means that applications which support integer scale factors
only will see integers only, also when QT_SCREEN_SCALE_FACTORS
specifies a fractional factor.

Users who want to override can set

  QT_SCALE_FACTOR_ROUNDING_POLICY=PassThrough

to restore the default Qt rounding behavior.

[ChangeLog][QtGui] The high-DPI scale factor rounding policy (settable with
QGuiApplication::setHighDpiScaleFactorRoundingPolicy() or
QT_SCALE_FACTOR_ROUNDING_POLICY) now applies to scale factors set
with QT_SCREEN_SCALE_FACTORS.

3f40a8b5b1 Add QTextListFormat::start: html and markdown ordered list index offset
This is useful for a lot of applications that render text coming from
sources which already support arbitrarily numbered lists (like chat
applications for example). Application-side workarounds usually have
significant overhead; and this feature has been requested multiple times.

It should be possible to both read and write HTML with the <ol start="x">
attribute, and read and write Markdown with arbitrary numbers for the
first item in a list.

[ChangeLog][QtGui] QTextList now supports specifying a start index using
the new QTextList::{setStart, start} functions. The HTML start attribute
on ordered lists in rich text documents is now parsed and used when
rendering a text list. Non-negative indices in markdown lists are now
also parsed and written properly. This allows starting a list with a
different number than 1.

4201cdab18 rhi: Metal tessellation shader input output interface blocks
Add support for shader input output interface blocks in Metal
tessellation pipelines.  This feature is builtin to other rhi supported
tessellation backends (OpenGL/Vulkan).

Metal tessellation is implemented as compute pipelines for vert and
tesc, and a render pipeline for tese and frag.  The shader conversion
from GLSL is handled by SPIRV-Cross, which has a particular way of doing
things.  Rhi must setup the vertex inputs for the tese - frag render
pipeline to read from buffers written by the tesc compute pipeline,
following SPIRV-Cross conventions.  This includes ensuring correct
memory alignment per MSL Specification.

In order to enable input output interface blocks, reflection of struct
members of QShaderDescription::InOutVariable is required.  Reflection of
QShaderDescription::BuiltinVariable array dimensions is also required to
support variable size tese builtin input gl_ClipDistance.

An acompanying patch to QtShaderTools is required.

8e27e31649 Add workaround for threeDimTexture case failing with some drivers
Not relevant for the CI as that does not run with any real Vulkan
implementation. (and Lavapipe works if that's used)

As the investigation in the Jira issue shows, there is no proper
conclusion yet on why rendering to a slice of a 3D texture breaks
the content of other slices that have image data written to them
before that render pass targeting the slice. It would seem that
transitioning to COLOR_ATTACHMENT_OPTIMAL has some unexpected
consequences for slices that are not targeted by the render pass
with Mesa on Intel.

(NB rendering to a given 3D texture slice works via
VK_IMAGE_CREATE_2D_ARRAY_COMPATIBLE_BIT; and how often this is needed
in practice is unclear, typical volume rendering cases will anyway
likely just upload data to the slices of a 3D texture, not rendering
to them)

The problem is still clearly visible in the tex3d manual test (when run
on affected Linux machines), this we keep unchanged for the time being
so that the issue can be examined further. However, the autotest is
changed to prevent the issue from occurring (render to slice first,
then upload to other slices) since it causes confusion when the test
is run locally on various developer machines.

fc33fea999 Don't do font merging for PUA characters

If these were used and the main font did not have support for them,

arbitrary selection of glyphs, based on whatever existed on the
platform. This is unexpected and different from how native apps

84fb0de413 rhi: Add D3D12 support
- The optional nice-to-haves DebugMarkers, Timestamps, PipelineCache
  are not yet implemented (features reported as false, to be
  implemented later, although buffer/texture resource name setting
  already works as-is, regardless of DebugMarkers).

- Mipmap generation for 3D textures is missing. Won't matter much
  given that 3D textures are not used in Qt for anything atm. For
  generating mipmaps for 2D (or 2D array) textures, the MiniEngine
  compute shader and approach is used. 3D support for the mipmap
  generator may be added later. 1D textures / arrays are supported
  except for mipmap generation, and so the
  OneDimensionalTextureMipmaps feature is reported as false.

- Qt Quick and Qt Quick 3D are expected to be fully functional.
  (unforeseen issues are not impossible, of course)

- Uses minimum feature level 11.0 when requesting the device. It is
  expected to be functional on resource binding tier 1 hardware even,
  although this has not been verified in practice.

- 2 frames in flight with the usual resource buffering
  (QRhiBuffer::Dynamic is host visible (UPLOAD) and always mapped and
  slotted, other buffers and textures are device local (DEFAULT).
  Requests 3 swapchain buffers. Swapchains are mostly like with D3D11
  (e.g. FLIP_DISCARD and SCALING_NONE).

- The root signature generation is somewhat limited by the SPIR-V
  binding model and that we need to map every binding point using the
  nativeResourceBindingMap from the QShader. Thus the root signature
  is laid out so each stage has its own set of resources, with shader
  register clashes being prevented by setting the visibility to a
  given stage.

  Sampler handling is somewhat suboptimal but we are tied by the
  binding model and existing API design. It is in a fairly special
  situation due to the 2048 limit on a shader visible sampler heap, as
  opposed to 1000000 for SRVs and UAVS, so the approach we use for
  textures (just stage the CPU SRVs on the (per-frame slot) shader
  visible heap as they are encountered, effectively treating the heap
  as a ring buffer) would quickly lead to having to switch heaps many
  times with scenes with many draw calls and sampledTexture/sampler
  bindings in the srb.

  Whereas static samplers, which would be beautiful, are impossible to
  utilize safely since we do not have that concept (i.e. samplers
  specified upfront, tied to the graphics/compute pipeline) in the
  QRhi API, and an srb used at pipeline creation may change its
  associated resources, such as the QRhiSampler reference, by the time
  the shader resources are set for the draw call (or another,
  compatible srb may get used altogether), so specifying the samplers
  at root signature creation time is impossible.

  Rather, the current approach is to treat each sampler as a separate
  root parameter (per stage) having a descriptor table with a single
  entry. The shader visible sampler heap has exactly one instance of
  each unique sampler encountered during the lifetime of the QRhi.

- Shader-wise no different from D3D11, works with HLSL/DXBC 5.0
  (i.e. existing .qsb files with DXBC in them work as-is). But unlike
  D3D11, this one will try to pick 6.7, 6.6, ..., down to 5.0 from the
  QShader, in that order.

- Uses D3D12MA for suballocating. As a result it can report vmem
  allocation statistics like the Vulkan backend, and it does more
  since the DXGI memory usage (incl. implicit resources) is also
  reported.  This is optional technically, so we also have the option
  of going straight with the heavyweight CreateCommittedResource()
  instead.  That is what we do if the adapter chosen reports it's
  software-based or when QT_D3D_NO_SUBALLOC=1 is set.

- PreferSoftwareRenderer (picking the WARP device) and the env.var.
  QT_D3D_ADAPTER_INDEX work as with the D3D11 backend.

- It is not unexpected that with large scenes that generate lots of
  draw calls with multiple textures/samplers per call the performance
  may be slightly below D3D11 (probably mostly due to descriptor
  management). Similarly, the reported memory usage will be higher,
  which is partly natural due to creating heaps, descriptor pools,
  staging areas, etc. upfront. Will need to be evaluated later how
  these can be tuned.

without adding it to the parent directory.

Refactor the test code to be data driven, add the image files as
external test data files, and adjust the test code to find the files.

Use the QTextImageFormat from the document rather than a manually
crafted one, as otherwise we don't test a real usecase.

This also makes the test more flexible for adding qrc, resources, and
file URLs.

Relevant mainly if we want to consistently expose these as the
theoretically correct uint32_t/quint32 from Qt Quick's
QSGRendererInterface. (not that int is not sufficient for
indexing the typical 3-4 families and 2-16 queues per family)

Some checks are not actually needed since the family index

ca64365e3a Don't hide object replacement char except in rich text
The object replacement character (U+FFFC) is used to represent
inline objects such as images in rich-text. To enable this,
we have special handling of it in QTextEngine. For classes
where inline images are not supported, it will just be hidden
from the visual text, which is unexpected.

Instead of always special-casing it, we make this dependent
on whether the document layout has registered any object handlers.
If they have not, then there will be no visual representation of
the object, and it is better to show the glyph for it.

For anything based on QTextDocument, there will always be the
image handler, so U+FFFC will still have special handling there,
but for non-rich labels and plain text editors the glyph will
be shown instead.

Note that there was also a bug in QLineEdit, where the object
replacement character was always replaced by a space. This was
introduced in 2007, in a patch which replaced a !ch.isPrint()
with a check for "the most obvious non-printable characters"
to reduce the number of characters that were not shown. However,
U+FFFC is a printable character and would thus not have been
filtered by the !isPrint() condition, so I think this was a
mistake at the time. However, due to the special-casing of
the character in Qt, it would not have had any effect until
now.

This also changes the QTextLayout::cursorToXForInlineObject()
test to actually test proper inline objects, as this was
previously using a hack which depended on the inline object
code to be used even for plain QTextLayouts with no handlers
for these.

[ChangeLog][Text] The object replacement character (U+FFFC)
is now only filtered out in rich text controls, where they
represent inline objects. In other controls, its glyphs will
be shown as with other text.

58907dfa81 Try to match variant-selector font to preceding character
Variant-selectors are special unicode symbols which are used to
modify glyph selection for the preceding character. For instance,
a regular symbol could be turned into a color emoji using VS16,
the emoji variation selector. In order for this to work, however,
the font that handles the selector has to handle the full pair of
characters, so that it can apply the correct substitution rules.

One specific example of this was on macOS, where an airplane
symbol + VS16 would match the symbol to the default UI font but
the VS16 to the emoji font. Since there string provided for the
emoji font did not have any preceding character for VS16, we just
ignored it.

To improve on this, we now detect variation selectors that have
been matched to different font engines than the preceding
character. When such a case occurs, we check if the selector font
also supports the preceding character, and if it does, we keep
the pair together and use the same font for both.

[ChangeLog][QtGui][Text] Fix some cases where a variation-selector
character would be ignored in font selection and the correct
variant of a character would thus not be selected.

12b7eab4d2 Detach event points when cloning pointer events
Input events that originate from actual device interaction should reflect the
device's state, and device and events need to be kept in sync so that event
sequences (such as multi-touch events, where we have begin/update/end cycles
spanning multiple events) are working correctly.

For that reason, the event point data in pointer events is explicitly shared,
and we only detach in exceptional situations. This saves us memory allocations,
and makes sure that the event point data carried by events, and the event point
data stored persistently in the device, are kept in sync.

Cloned pointer events do not originate from device interactions, and should
therefore not sync back to the device. E.g. accepting a clone should not modify
the original event data stored in the device. There are exceptions here as
well, e.g. when cloning an event in Qt in order to deliver a translated version
of it to a different scene. Different points might even get delivered to
different scenes or windows, or at least different items in the same scene. For
that reason, we explicitly detach, and then explicitly write back the relevant
states after the cloned event has been delivered.

But in general, we should assume that cloned events do not write back to the
device. Since QEventPoint is an explicitly shared data type that never detaches
itself, we have to explicitly detach it when making copies that should not be
shared.

The ideal implementation of this would be to do the detach in the copy
constructor of QPointerEvent, which is called when cloning. However, Qt itself
makes copies of QPointerEvent without using clone, e.g. when assembling lists
of touch events for the different subscenes or windows in
QGuiApplicationPrivate::processTouchEvent, where event objects are added to a
QVarLengthArray<QMutableTouchEvent>. This makes copies, and those copies must
not detach.

So we have to implement the special cloning behavior in each override of
QPointerEvent::clone(). For this, introduce a dedicated macro for the common
member functions. This macro must be used for QPointerEvent subclasses.

c9d991de1f Fix missing text when Harfbuzz fails to shape a substring
This amends fccd419dd6.

If Harfbuzz failed on one of the items in a string and returned
zero glyphs, then we would exit the shaping loop. The mentioned
change fixed a crash related to this when the ignored character
was the only character in the string, but it occurred in a
subitem of a longer string, then we would return and fail to
lay out the rest of the string.

This popped up recently because an update to Harfbuzz has caused
it to return zero glyphs when applying the Apple emoji font to
an isolated variant character (see bug report). When we matched
the symbol to the main font and only the variant character to
the emoji font, we would get in this situation, and end up
exiting the shaping early.

[ChangeLog][QtGui][Text] Fixed a regression which would
sometimes cause text to disappear if the string contained
an unmatched variation selector character.

0dcd640a1f Don't return a visual glyph for ignorable characters
When Harfbuzz returns zero glyphs, this will typically be because
the character is ignored. We currently have no way to differentiate
this from actual error cases, so to avoid return the error glyph
for cases which are not really errors, we set the dontPrint flag
for this.

When we add a way to differentiate between error cases and non-error
cases later, we should revert this for the actual errors.

This is improved version of previous fix
013c346a8d that was reverted because it

hadn't been wrapped) in layout data (layoutData->currentMaxWidth).
Then when the next line is explicitly wrapped by line or paragraph
separator, this accumulated width will be used to adjust layout's
maximum width.

649dccf57b Reintroduce converter APIs for supporting native clipboard formats
In Qt 5, QWin(dows)Mime and QMacMime lived in the respective Extras
modules, which were removed and partially folded into the relevant
modules in Qt. QWindowsMime and QMacMime continued to provide the
abstraction for implementing built-in support for native clipboard
formats and UTIs within Qt, but only as private APIs.

After the recent clean up of those APIs and respective infrastructure,
we can now bring them back as public converter interfaces. Application
developers can subclass those and instantiate an instance of their
implementation to add support for platform or application specific
data formats.

These interfaces are not in the QNativeInterface namespace, as
applications don't call into Windows or macOS using those interfaces.
I.e. there is no class on which an application would call

  auto *converter= nativeInterface<QWindowsMimeConverter>();

Also, since applications override those converter types, we do want to
guarantee binary and source compatibility.

[ChangeLog][QtGui][QWindowsMimeConverter] Reintroduced to allow
applications to add support for conversion from and to Windows-native
clipboard formats to MIME-encoded data.

[ChangeLog][QtGui][QUtiMimeConverter] Reintroduced to allow
applications to add support for conversion from and to clipboard data on
