When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.
We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).
As a nice side effect, performance (and in particular scalability)
is improved.
Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
worse. Additionally, it also required a rather egregious hack to
handle the (pathological) case of a single thread talking to both
ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
posting wake-up events to its event loop, and handling I/O on the
main thread; this performed roughly like this solution, but scaled
half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
and still handling I/O on the main thread; this still performed
comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
faster with big amounts of data, but scaled slightly worse, and the
diverging implementations were deemed not desirable.

This was added by 9ff76c27b9 on

0 glyphs, it just means it is unable to shape the string, for instance
if the input string only contains default ignorables (like a ZWJ)
and does not have any appropriate glyph to use for replacement.
Qt expects there to always be at least one glyph in the output
(num_glyphs == 0 is used to indicate shaping is not yet done), so
to avoid asserts later on, we simply populate the output with a
single 0 token, which is a required entry in the font that is
reserved for representing unrepresentable characters.
This also adds a test and therefore a zero-width joiner to the test

Add QRhi APIs to retrieve and reload the contents of the "pipeline
cache".
The only API where there is a true pipeline cache is object is Vulkan
(VkPipelineCache). For OpenGL, the other backend where we support this,
it is simulated with program binaries. The Qt 5 style OpenGL program
binary disk cache continues to work like before, but one has now the
option to do things in a more modern, graphics API agnostic way, that
leads to generating a single blob instead of a large set of files in
some system location, allowing easier "pre-baking" of the cache content.
It is expected that Qt Quick exposes the two new functions in form
if QSG_RHI_ environment variables, thus allowing easy testing and
cache file generation.
As an example for the performance improvements this can give, consider
Vulkan, where we do not have any existing persistent caching mechanism
in place:
Running BenchmarkDemoQt6.exe --scene flythrough --mode demo creates 18
QRhiGraphicsPipeline objects from Qt Quick and Qt Quick 3D.
The total time spent in QRhiGraphicsPipeline::create() during application
startup for these 18 pipelines is 35-40 ms on a given Windows (NVIDIA)
system.
When exporting the pipeline cache contents to a file, and then, in a
subsequent run, reloading the cache contents, this is reduced to 5-7 ms
on the same system, meaning we get a 6-7x improvement.
The generated data is always specific to a given Qt version, RHI
backend, graphics device, and driver version. Much of the implementation
consists of adding and verifying the appropriate header to the blobs
retrieved from the driver, to allow gracefully ignoring data that was
generated with a device or driver that differs from the one used at
run time. This should provide robustness, even if the Vulkan or OpenGL
implementation is for some reason not prepared to identity and reject
incompatible cache/program blobs.

This also needs improvements to qvkgen. What we get with this patch
are the Vulkan 1.1 and 1.2 core API's additional 11 instance-level
and 30 device-level commands present in QVulkanFunctions and
QVulkanDeviceFunctions.
All of these are attempted to be resolved upon construction. When the
implementation does not return a valid function pointer for some of them
(e.g. because it is a Vulkan 1.0 instance or physical device), calling
the corresponding wrapper functions will lead to unspecified behavior.
This is in line with how QOpenGLExtraFunctions works. The simple
autotest added to exercise some Vulkan 1.1 APIs demonstrates this in
action.
The member functions in the generated qvulkan(device)functions header
and source files are ifdefed by VK_VERSION_1_{0,1,2}. This is essential
because otherwise a Qt build made on a system with Vulkan 1.2
headers would cause compilation breaks in application build environments
with Vulkan 1.0/1.1 headers when including qvulkanfunctions.h (due to
missing the 1.1/1.2 types and constants, some of which are used in the
function prototypes). In practice this should be alright - the only
caveat to keep in mind is that the Qt builds meant to be distributed
to a wide variety of systems need to be made with a sufficiently new
version of the Vulkan headers installed, just to ensure that the
1.1 and 1.2 wrapper functions are compiled into the Qt libraries.

it calls QWindowSystemInterfacePrivate::fromNativeTouchPoints to

Therefore we must give that function touchpoints that are actually in

From QRhi's perspective this consists of two things:
- A shader with samplerExternalOES in it cannot go through the standard
pipeline. Rather, a QShader with suitable GLSL code in it has to be
constructed manually. As this is something useful as an autotest
anyway, add a test case to the qshader autotest that demonstrates
this.
- When it comes to correctly calling glBindTexture, add a QRhiTexture
flag. The expectation is that an OpenGL-only client sets this in
combination with QRhiTexture::createFrom(), thus wrapping an existing
texture that then gets bound to the GL_TEXTURE_EXTERNAL_OES target
instead of our usual GL_TEXTURE_2D.
For completeness we also add a SamplerExternalOES variable type to
QShaderDescription, but the sampler type is not actually used by the
QRhi OpenGL backend, as it is the QRhiTexture that defines the
texture target.

When a foreign event loop that does not enter an alertable wait state
is running (which is also the case when a native dialog window is
modal), pipe handlers would freeze temporarily due to their APC
callbacks not being invoked.
We address this problem by moving the I/O callbacks to the Windows
thread pool, and only posting completion events to the main loop
from there. That makes the actual I/O completely independent from
any main loop, while the signal delivery works also with foreign
loops (because Qt event delivery uses Windows messages, which foreign
loops typically handle correctly).
As a nice side effect, performance (and in particular scalability)
is improved.
Several other approaches have been tried:
1) Using QWinEventNotifier was about a quarter slower and scaled much
worse. Additionally, it also required a rather egregious hack to
handle the (pathological) case of a single thread talking to both
ends of a QLocalSocket synchronously.
2) Queuing APCs from the thread pool to the main thread and also
posting wake-up events to its event loop, and handling I/O on the
main thread; this performed roughly like this solution , but scaled
half as well, and the separate wake-up path was still deemed hacky.
3) Only posting wake-up events to the main thread from the thread pool,
and still handling I/O on the main thread; this still performed
comparably to 2), and the pathological case was not handled at all.
4) Using this approach for reads and that of 3) for writes was slightly
faster with big amounts of data, but scaled slightly worse, and the
diverging implementations were deemed not desirable.

QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).
David provided the perfect example:
if (str == 123) { ~~~ }
compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.
Add a macro to revert to the implicit constructors, for backwards
compatibility.
The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.
[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.

Bring QPixmapIconEngine on par with QIconLoaderEngine

factor a test parameter during icon lookup.
This allows storing e.g 16x16@1, 16x16@2, 16x16@3 versions
of a pixmap in the icon, and then having QIcon select
the correct one based on the target devicePixelRatio.
Extend the qiconhighdpi test to also cover QPixmapIconEngine,

The corner cases of pixmap lookup can be much complicated.
QIconLoaderEngine and QPixmapIconEngine should ideally

In 4e400369c0 we deprecated
normalizedPos() because we suspect it's a legacy feature that few
users will need. However Qt developers keep bringing up the continued
usage in autotests over and over. (It's IMO not wrong to keep testing
deprecated functions in autotests, but the warning keeps attracting
attention.)
Of course it will turn out that normalizedPos() has users; we just
don't know how many. One way to look at it is: why should they copy
a snippet of code to calculate it, when it costs us so little to
continue to provide this accessor.
It might also turn out that some users will complain that in Qt 5
it was passed through from the device driver (or at least from the
window system API) to the application, and perhaps the replacement will
not always work, for example if availableVirtualGeometry() ends up
wrong, or there is some strange scenario that generates events that are
out-of-bounds for the device that the event professes to come from, so
that the "normalized" coordinates also go outside the [0..1] range.
We reserve the right to put back the storage in QEventPointPrivate if
the need arises; so that's why this function is not inline.
We continue to hope that startNormalizedPos() and lastNormalizedPos()
are used even less and won't be missed much, because it would be
wasteful to store them all the time if only a few users need them.

In Qt Quick, when we deliver an item-specific QTouchEvent that contains
only the subset of eventpoints that are inside the Item's bounds,
traditionally the Item can accept the event to tell the delivery logic
that the event is handled and doesn't need to be delivered further.
But an Item cannot be expected to have total scene awareness; so now,
the delivery is "done" only when all eventpoints in the original event
are accepted. This behavior has been working well enough already due to
logic in QQuickWindow that iterates the points and accepts them if the
event is accepted; but it seems appropriate to move this enforcement
into QPointerEvent itself. Making setAccepted() virtual gives us a
useful degree of freedom.
Event-handling code should alternatively use QEventPoint:setAccepted()
or QPointerEvent::setExclusiveGrabber() to take resonsibility for only
a subset of the touchpoints.
Another way to put it is that we treat QPointerEvent::setAccepted() as a
convenience method: accepting the QEventPoints is what counts (at least
in Qt Quick).
