8359e44324 Offscreen: Fix implementation of QScreen::grabWindow
If id == 0, then we should grab the specified rect from the screen.

To do that, find all windows intersecting with the screen geometry, and
compose their backing store images into a screen-size pixmap.

Otherwise, find the respective backing store and grab only that.

Remove the old code respecting the desktop widget, which is no longer a
thing in Qt 6. The code was also wrongly grabbing only the first
containing - not intersecting - window's backing store into the screen
pixmap.

Enable the QScreen::grabImage test for the offscreen platform, where it
now passes.

6ffc8d8eb6 QtGui/math3d: Fix QQuaternion::getEulerAngles for GimbalLock cases
This is heavily inspired by the patch written by Inho Lee
<inho.lee@qt.io>, which says "There is a precision problem in the
previous algorithm when checking pitch value. (In the case that the
rotation on the X-axis makes Gimbal lock.)"

In order to work around the precision problem, this patch does:

 1. switch to the algorithm described in the inline comment to make
    the story simple.
 2. forcibly normalize the {x, y, z, w} components to eliminate
    fractional errors.
 3. set threshold to avoid hidden division by cos(pitch) =~ 0.

From my testing which compares dot product of the original quaternion
and the one recreated from Euler angles, calculation within float range
seems okay. (abs(normalize(q_orig) * normalize(q_roundtrip)) >= 0.99999)

Many thanks to Inho Lee for the original patch and discussion about
rounding errors.

cb27ed30f7 QCSS: Support Qt 5-style integer property selectors
In Qt 5 style sheets, objects could be selected by an enum-type property
using the integer value of the enum value, e.g

QToolButton[popupMode="1"] { ... }

In Qt 6, the the new meta type system and QVariant implementation enabled
QVariant::toString to return the string representation of the enum value
instead for a property containing an enum. Since QStyleSheetStyle's
attribute matching is string based, this breaks the Qt 5 style selector,
and QCSS code instead needs to use e.g.

QToolButton[popupMode=MenuButtonPopup] { ... }

While the new syntax is arguably preferable, this is an unintentional
change that silently breaks style sheet code (no error or warning at
compile- or run-time).

To support Qt 5-style selectors, we have to change the StyleSelector
interface of the QCssParser API so that we can pass through what type
of value the attribute extractor should return; if an integer string "1"
is provided, then we need to compare the enum integer value; if the
string provided does not represent a number, then we need to compare the
name of the enum value.

Since the pure virtual attribute() method that needs to be implemented
to extract the attribute value of the node is implemented in modules
outside qtbase, add a second virtual method that takes the entire
QCss::AttributeSelector, which includes the value to match. Extractor
implementations can use it to evaluate which type of data to return for
an exact match. The default implementation calls the old attribute()
method so that existing StyleSelector implementations continue to work.

Make the respective change in the QStyleSheetStyleSelector, and simplify
the surrounding code. Adjust other StyleSelector implemnentations in
qtbase. As a drive-by, remove the superfluous virtual declaration from
those overrides.

Once submodules are adjusted to override this virtual function instead
of the (now no longer pure) virtual attribute() method, that method can
be removed.

cfca4188f9 tests: port to new QMutableEventPoint static API
This code didn't actually use QMutableEventPoint::from(), so didn't
run into the UB that from() depended on, but it's in the way of making
QMutableEventPoint a befriendable namespace instead of a public

Replaced the QMutableEventPoint ctor that takes a timestamp, and
therefore isn't compatible with the ctors on QEventPoint, with a
static function that returns QEventPoint instead.

Port QList initialization to braced-initialization as a drive-by.

17dca04a61 Use QTextCharFormat::fontFixedPitch to remember Markdown backtick spans
If the editing app (like qtbase/examples/widgets/richtext/textedit)
has controls only for setting a specific font, and someone uses it to
write markdown "from scratch", then we need to detect that they chose
Courier or some other fixed-pitch font, and write the backticks,
because Markdown has no syntax for selecting a specific font family.
If the user loads markdown into such an application, the font
is set to QFontDatabase::systemFont(QFontDatabase::FixedFont).
Round-trip editing was already working, as long as such a font exists.
QTextCharFormat::setFont() calls setFontFixedPitch(font.fixedPitch()),
but for the chosen "mono" font, font.fixedPitch() can be false.
For semantic completeness and separation of concerns, we now
set fontFixedPitch explicitly if a `backtick` span is encountered.
As a followup to f1e60de665 this
should get its autotest passing reliably.

0a59101495 rhi: Add support for separate image and sampler objects
For Direct 3D, Metal, and Vulkan this is natively supported. (and
makes no difference in particular for D3D and Metal because they do
not have the legacy combined image sampler concept anyways)

With OpenGL it will work too, but this relies on SPIR-Cross magic and
is still using a combined sampler (e.g. a sampler2D) in the GLSL
shader. The GL backend walks back and forth in the mapping tables from
the shader baker in order to make this work, which is presumably
slightly more expensive than combined image samplers.

Do note that combined image samplers (i.e. sampler2D in the shader and
QRhiShaderResourceBinding::sampledTexture() in code) continue to be
the primary, recommended way for any user of the rhi for the time
being.

9ea1f0f8b9 Fix qobject_cast on partially destroyed QWidget/QWindow
QWidget and QWindow use bits in QObjectPrivate to provide for a couple
of shortcuts -- one in qobject_cast, and another in the isWidgetType() /
isWindowType() functions in QObject. These can be optimized by simply
looking at the bits, without actually doing more expensive runtime
casts.

These bits were set on construction, but not unset on destruction.  The
result was for instance that destroying a QWidget would report that the
object was still a QWidget when ~QObject was reached.

Fix this

1) by setting the bits only when QWidget / QWindow constructors start;

2) by resetting the bits once ~QWidget / ~QWindow are completed.
Technically speaking this is not 100% correct in the presence of data
members, but luckily those classes don't have any.

Amend an existing test for QWidget (whose comment said exactly the
opposite of what the test actually did) and add a test for QWindow.

Some other code was wrongly relying on isWidgetType() returning true
for destroyed QWidgets; amend it as needed.

[ChangeLog][QtCore][QObject] Using qobject_cast on partially constructed
or destroyed QWidget/QWindow instances now yields correct results.
Similarly, using the convenience isWidgetType() / isWindowType()
functions now correctly return false on such instances. Before,
qobject_cast (and the convenience functions) would erroneously report
that a given object was a QWidget (resp. QWindow) even during that
object's construction (before QObject's constructor had completed) or
destruction (after QWidget's (resp. QWindow's) destructors had been
completed). This was semantically wrong and inconsistent with other ways
of gathering runtime type information regarding such an object (e.g.
dynamic_cast, obj->metaObject()->className() and so on).

23f8d6c57f rhi: Drop the profiler for now
The system we inherited from the original Qt 5.14 introduction of QRhi
is a text stream based solution where resource creation and frame
timings are sent in a comma-separated format to a QIODevice.

This, while useful to get insights about the number of resources at a
given time, is not actively helpful. The frameworks built on top (Qt
Quick, Qt Quick 3D) are expected to provide solutions for logging
timings in a different way (e.g. via the QML Profiler). Similarly,
tracking active resources and generating statistics from that is
better handled on a higher level.

The unique bits, such as the Vulkan memory allocator statistics and
the GPU frame timestamps, are converted into APIs in QRhi. This way a
user of QRhi can query it at any time and do whatever it sees fit with
the data.

When it comes to the GPU timestamps, that has a somewhat limited value
due to the heavy asynchronousness, hence the callback based
API. Nonetheless, this is still useful since it is the only means of
reporting some frame timing data (an approx. elapsed milliseconds for
a frame) from the GPU side.

04cdde30d6 rhi: Enable exposing separate image and sampler objects from the shader
Adds the following in a QShader/QShaderDescription:

- a list of separate images
- a list of separate samplers
- a list of "combined_sampler_uniform_name" -> [
  separate_texture_binding, separate_sampler_binding ] mappings
  (relevant for GLSL only)

On the QShader (and qsb/QShaderBaker) level not having separate image
(texture) and sampler objects exposed in the reflection info is not
entirely future proof. Right now we benefit strongly from the fact
that Vulkan/SPIR-V supports both combined and separate
images/samplers, while for HLSL and MSL SPIRV-Cross translates
combined image samplers to separate texture and sampler objects, but
it is not given that relying on combined image samplers will always be
possible in the long run; it is mostly a legacy OpenGL thing that just
happens to be supported in Vulkan/SPIR-V due to some benefits with
certain implementations/hw, but is not something present in any newer
APIs.

In addition, before this patch, attempting to run a shader with
separate textures and samplers through qsb will just fail for GLSL,
even though SPIRV-Cross does have the ability to generate a "fake"
combined sampler for each separate texture+sampler combination. Take
this into use. This also involves generating and exposing a
combined_name->[separate_texture_binding,separate_sampler_binding]
mapping table for GLSL, not unlike we have the native binding map for
HLSL and MSL. A user (such as, the GL backend of QRhi) would then use
this table to recognize what user-provided texture+sampler binding
point numbers correspond to which auto-generated sampler2Ds in the GL
program.

Take the following example:

layout(binding = 1) uniform texture2D sepTex;
layout(binding = 2) uniform sampler sepSampler;
layout(binding = 3) uniform sampler sepSampler2;

Inn the reflection info (QShaderDescription) this (assuming a
corresponding qtshadertools patch in place) now gives one entry in
separateImages() and two in separateSamplers().  Assuming sepTex is
used both with sepSampler and sepSampler2, the GLSL output and mapping
table from QShaderBaker will have two auto-generated sampler2Ds (and
no 'texture2D' or 'sampler').

One immediate benefit is that it is now possible to create a shader
that relies only on separate images and samplers, feed it into qsb,
generate all the possible targets, and then also feed the SPIR-V
binary into a tool or library such as Tint (e.g. to generate WGSL)
that canot deal with combined image samplers.

b369dc6021 QTextHtmlParser: fix prefix lookahead and html comments

When it's obvious from the codebase that it should actually look ahead
of the current character being processed, and compare againt that future
character.

Html comments were also not handled quite right. Partially because of
the broken hasPrefix() function, but also because it would advance the
current index tracker by 3 instead of 2. Remember that the beginning of
an html comment is <!-- meaning that there are only supposed to be 2
dashes required, not 3. The result would be that something like this
<!----> would not automatically close, because the current index tracker
would jump over the first 3 dashes when it begins a comment, and the
remaining unprocessed string would be ->

Also, because of the broken lookahead in hasPrefix(), a comment could
actually be started with just <!- not requiring a second dash at all.

previously ignored for all values except "screen".

To use a media rule other than the default "screen" rule,
specify it before calling setHtml() with setMetaInformation()
and the new info value 'CssMedia'.

ae6dc7d6df Fix qt_scrollRectInImage when scrolling outside of the image
We were clipping the source rect to the image, both pre and post
scrolling, but did not apply the same logic to the target position.
By computing the target position based on the already clipped source
rect we ensure that the target position is also correct.

This was causing valgrind warnings on Linux, and crashes on Windows,
when trying to test the lower level QBackingStore::scroll() function.
The reason we were not seeing this in practice was that QWidget does
its own sanitation and clipping of the arguments before passing them
on.

As a drive-by, fix the access of image to use constBits instead of a
manual cast, and rename variables to better reflect their use.

bc4570ed24 rhi: Auto-rebuild rt by tracking attachment id and generation
Unlike the shader resource binding lists that automatically recognize
in setShaderResources() when a referenced QRhiResource has been rebuilt
in the meantime (create() was called i.e. there may be completely
different native objects underneath), QRhiTextureRenderTarget has no
such thing. This leads to an asymmetric API and requires also rebuilding
the rt whenever an attachment is rebuilt:

rt = rhi->newTextureRenderTarget({ { texture } })
rt->create()
cb->beginPass(rt, ...)
texture->setPixelSize(...)
texture->create()
rt->create() // this should not be needed
cb->beginPass(rt, ...)

Avoid having to do that second rt->create().

6f542f19bf QFontDatabase (Windows): Sanitize font requests early
After the windows font engine was no longer marking everything as
scalable we started limiting the font size of requests to the maximum
of Courier when it was requested. This was a regression from 5.8 and not
in agreement with our documentation.

The problem is that we would only make the switch from Courier to
Courier New after having already gone through the foundry-lookup and
found a closest-available font size for Courier.

With this sanitization step in the backend we can make these changes
early enough that we haven't yet adjusted e.g. the font size.

56bd1b76d2 Don't change resolve mask when setting brush doesn't change palette
After 556511f9f3, which moved the resolve
mask storage into the palette's d-pointer, modifying the resolve mask
requires a detach. As of now, we only detached when setting a different
brush, but always modified the resolve mask, which broke palettes that
shared the d-pointer (likely the global default palette).

However, detaching has negative side effects when styles set brushes on
temporary palette objects and then use that palette object's cache key
to build a cache of pixmaps. As each drawing would detach the palette
(even if the palette doesn't change, which is likely), the cache key
changes with each detach, and the cache would quickly increase in size.
This was addressed in changes d7bcdc3a44
and 1e75dcf251.

We can either detach and find other ways to address the issues from
QTBUG-65475, or we can not change the resolve mask when the brush doesn't
change and completely ignore the call.

Since QFont ignores the setting of any attribute to a value that is
identical to the current value, and since it's possible to force that
the resolve-bit is set by calling setBrush twice with different brushes,
ignoring the call seems like the better solution.

[ChangeLog][QtGui][QPalette] Setting a brush on a palette that is
identical to the current brush no longer sets the resolve mask bit for
that particular role, so items using the palette will continue to
inherit changes from parent items.

6b02473e1e Fix overlapping text for Osaka font on macOS
The Osaka font on macOS has all zeroes in the OS/2 table, probably
because it is not intended to be cross-platform. In Qt 6 (since
f761ad3cd9) we are trying using the
same vertical metrics on all platforms, but this only works if
they are valid.

To work around this issue, we detect the case when ascent/descent
values are both 0, since this is very unlikely to be intentional,
so we fall back to the system-provided ascent and descent in these
cases.

Adding the test also revealed that we had missed the check for
a macOS-specific bitmap font format when skipping the check for
bitmap fonts in 7a18b7e2c2.

font would lead to overlapping text.

71faedc5b4 Fix deserializing Qt 5.x fonts through QDataStream
In Qt 5, fonts had both singular family and plural families properties,
and both were stored separately when streaming through QDataStream. The
families list was treated as an extension of family in this case, and
the primary font family was always the singular family property.

In Qt 6, it has been merged into one and family() is now just a
convenience for families().at(0).

But when reading files generated with Qt 5, we would ignore the fact
that these were previously separated. We would first read the family
entry into the families list, and then we would later overwrite this
with  an empty families list.

Instead, we detect streams created with Qt 5.15 or lower and make sure
we append the families list instead of overwriting it in this case. In
addition, we need to make sure we split up the list again when
outputting to Qt 5.x.

This adds a file generated with QDataStream in Qt 5.15 to the test to
verify.

[ChangeLog][Fonts] Fixed a problem deserializing the family of fonts
that had been serialized using QDataStream in Qt 5.

Arrays of textures have always been supported, but we will encounter
cases when we need to work with texture array objects as well.

Note that currently it is not possible to expose only a slice of the
array to the shader, because there is no dedicated API in the SRB,
and thus the same SRV/UAV (or equivalent) is used always, capturing
all elements in the array. Therefore in the shader the last component
of P in texture() is in range 0..array_size-1.
