7cbac745dc rhi: Returns mapping tables by value from QShader
As these are QList and QHash. All existing usages are based on this
anyway, no value in being able to indicate "not available" - an empty

f1e60de665 QTextMarkdownImporter: don't apply text char format to list item block
We want an ordered list item's number to be rendered with default char
format, like the others in the same list, even if the list item's text
begins with a span that has a different char format.  So insert the
list item's block with a default char format first, then change the
char format of the cursor to suit the text that's about to be inserted.
In HTML interpretation, it means the <li> does not have a style, but
contains a styled span.

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
The hasPrefix() function would only use the second 'lookahead' parameter
to check if there was more unparsed text after the current character.
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.

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().

After the windows font engine was no longer marking everything as
scalable we started limiting the font size of requests to the maximum

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

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

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.

e7a1fbfc47 rhi: Add texture array support
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.

df359bcb70 Decouple quitOnLastWindowClosed from quitLockEnabled
In a512e210ac5b032c5fc2edf1ddf72e5a414485fda512e21 quitOnLastWindowClosed
was changed to be implemented in terms of quitLockEnabled, but without
any documentation to that end.

Although the two features are similar (automatic quit under certain
conditions), and interact, it doesn't make sense to overlap them until
we actually expose them as a single property (automaticQuit e.g.)

The logic for determining whether we can can quit automatically has
been refactored to take both properties into account, on both a Core
and Gui level. The call sites still need to check the individual
properties to determine whether to activate automatic quit for
that particular code path.

5335cc4a5a Fix cursor positioning on bidi boundaries
When the cursor is positioned between to script items that have different
writing directions, prioritise the script item that has the same direction
as the paragraph (i.e. the QTextEngine) when deciding where and how to
display the cursor. If visual cursor movement is enabled, the behavior is
unchanged.

f54044d4a9 Fix cursor placement at left and right ends of bidi text
In a text line that has a change of direction at either end of the text,
the cursor needs to be positioned where the next character is inserted,
or where backspace deletes the previous character. In bidi text, this is
ambiguous as illustrated by this example:

abcشزذ

Depending on whether this string was typed in a left-to-right document
or in a right-to-left document, it could be first latin, then arabic; or
it could be first arabic, then latin.

If a general left-to-right context, cursor position 0 should be in front
of the 'a', and cursor position 6 should be at the end of the arabic
text, in the visual middle of the line. Cursor position 3 can be either
after the 'c' if the next character typed would be latin, or at the
visual end of the line if the next character will be arabic.

Qt calculated the cursor position past the right end of the text as 3
(which is not wrong, but 3 has two visual positions), and placed the
cursor at the visual end of the line (favoring the right-to-left
alternative). Backspace would then delete the 'c', writing a new
latin character would insert a 'd' next to the 'c', writing a new arabic
character would insert it also in the middle - none of these operations
happen at the visual end of the line, where the cursor was blinking.

To fix this, we take into account the general layout of the text, which
is typically based on the document, or the user's locale setting and UI
translation, and calculate the cursor position accordingly: if we are
past the visual end of the document on either side, then the cursor
position is either 0 or the last character of the text, depending on the
direction of the QTextEngine used. This way, the cursor ends up in the
middle of the document when we click beyond the end of the line, which
is where characters are removed and inserted. Typing a 'd' at this point
will make the cursor jump to the end, where the d is added.

There are still corner cases: clicking on the right-most arabic character
calculates the cursor position as 3, which is then ambiguous, as it can
be either at the visual end of the string, or next to the 'c'. َQt makes
the inconsistent choice to place the cursor at the visual end, showing
the left-to-right indicator, but pressing a 'd' adds the 'd' after the
'c' in the middle of the text.

5e55297ee0 Markdown writer: indent fence consistent with code block
- Under a list item, we've been indenting code blocks:
  ```
  int main() ...
  ```
- But it's also ok *not* to indent (and github handles that better):
```
int main() ...
```
- There was a bug that when the code is not indented, the fence would be
  indented anyway:
  ```
int main() ...
  ```
  and that was not OK, neither for md4c nor for github.

Now with this change, either way is rewritable: you can read markdown
into QTextDocument, make small edits and write it back out again, with
the indentation being preserved (the code block is either part of the
list item, thus indented, or else it's outside the list completely).

8513bcd90c Fix caching of parsed border color values in CSS parser
When parsing CSS, a border-color value is parsed as four brushes, as css
allows assigning up to four values, one for each side.

When applying the CSS to the HTML, we accessed it as a color value,
which overwrote the parsed value with a QColor. So while we had a valid
parsed value (and didn't re-parse), the code accessing that value still
expected it to be a list, and thus failed to retrieve the data.

There are several ways to fix that, but the cleanest way without
introducing any performance penalty from repeatedly parsing (and in fact
removing a parse of the string into a color) is to enable colorValue to
interpret an already parsed value that is a list without overwriting the
parsed value again. To avoid similar issues in the future, add assert
that the parsed value has the right type in brushValues.

As a drive-by, speed things up further by making use of qMetaTypeId
being constexpr, which allows for it to be used in a switch statement.

Add a test case.

b4bb3a5415 Introduce QDoubleValidator::setRange overload with two parameters
The QDoubleValidator::setRange() used to have 3 parameters, with
the third one (the number of decimals) having a default value of 0.
Such default value does not make much sense for a *double* validator.
Also, since a default value was used, omitting the decimals was
silently overwriting the previous decimals value, discarding the
value that could be previously explicitly specified by user.

[ChangeLog][QtCore][QDoubleValidator][Important Behavior Changes] The
QDoubleValidator::setRange() method now has two overloads.
The first overload takes 3 parameters, but does not support a
default value for decimals.
The second overload takes only two parameters, not changing the
number of decimals at all.
Hence, the number of decimals will only be changed if the user
explicitly specifies it.
To maintain the old behavior of setRange(), pass 0 as the 3rd
argument explicitly.

Note that it is a source-incompatible change. But it should be fine,
because using QDoubleValidator with 0 digits after decimal point does
not make much sense and so, hopefully, is not that common.

At the same time, change the default-constructed QDoubleValidator
to use -1 for decimals, which allows arbitrarily many digits in
the fractional part. The value was previously 1000, which allowed
more than anyone would reasonably use, so this should make no
practical difference.

Some more unit tests to cover the behavior of the setRange()
overloads are also added.

As a dirve-by: remove unnecessary QValidator::State to int conversions
in the unit tests. QCOMPARE is capable of comparing these enums and
provides a better output in case of failure for enums.
