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

But the line is easily reachable by user code. If Harfbuzz returns
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
font to reproduce the issue.

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.

QGuiApplicationPrivate::processMouseEvent() sends a

A QPA TouchEvent always contains native touch points, which is why
it calls QWindowSystemInterfacePrivate::fromNativeTouchPoints to
translate the QMouseEvent's device-independent position back to the
raw position that it would have had if it came from a real touchscreen.
Therefore we must give that function touchpoints that are actually in
native coordinates.
It may be that some of this transformation could be avoided entirely,

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.
