Thiago Macieira 4252207e8f Use QThread::isMainThread() in a few places
It's thread-safe, whereas trying to load qApp isn't in Qt 6.x (will be
in 7.0) and dereferencing it to call QObject::thread() will probably
never be. It's also faster, being a single function call instead of two
or three.

This is not an exhaustive search, it's just a few places I found while
searching for QThread::instance().

Volker Hilsheimer d2730bc303 Logging: use qCDebug/Warning/Info when for categorized logging
When building qt with QT_NO_DEBUG/WARNING/INFO_OUTPUT set, then the
qDebug/Warning/Info macros expand to `QMessageLogger::noDebug`. That
helper is not defined to take a logging category or category function,
so using `qDebug(lcX, ...)` breaks the build. The correct way to emit
categorized logging is to use the qCDebug/Warning/Info macros.

The legacy QWindow convenience subclass does not have the
robust logic that was later implemented for the Vulkan backend of
QRhi. (i.e., never trust the QWindow; problem with QVulkanWindow
is that it half-trusts those values still, which leads to the
classic pixel-size-differs-by-one problem)

Laszlo Agocs bd78047df3 QVulkanWindow: Add a way to control post-1.0 Vulkan features
So now instead of filling out a VkPhysicalDeviceFeatures and
sending it in via VkDeviceCreateInfo::pEnabledFeatures,
we rather create a VkPhysicalDeviceFeatures2, which contains
a VkPhysicalDeviceFeatures (for 1.0 stuff) and a pNext
chain, and chain it via pNext to the VkDeviceCreateInfo.

QVulkanWindow will not do anything with post-1.0 features
by default. (in this regard it deviates from the QRhi
Vulkan backend which already tackles 1.1, 1.2, and 1.3
features as well, but this is not going to change)

However, applications may want to enable some of those still.
To enable this, add a new callback. When set, the callback is
invoked and the alternative behavior described above is
activated.

Marc Mutz aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

Laszlo Agocs f6dc0b4b20 Skip potentially costly features in QVulkanWindow
QVulkanWindow has recently been updated both in 5.15 and 6.x to start
enabling at least the 1.0 core features, because modern validation
layers are likely to complain if a feature is used without the
corresponding flag enabled upon device creation, even if the driver does
not actually care.

There is a catch here however, namely that some features may be true
opt-in flags, e.g. robustBufferAccess, and when enabled, they may incur
a performance penalty. So we will keep that one feature disabled even
when it is reported as supported.

It is unfortunate that VkPhysicalDeviceFeatures mixes together flags
that are most likely used only to query if some feature is supported by
the implementation while not serving as a real toggle (because opting
in/out is meaningless for the implementations in practice), and flags
that have significant effects when the feature is enabled, for example
when it comes to performance.

As QVulkanWindow only cares about 1.0, and 1.1+ features are to be
handled by the application via the features-modifier callback, we can
get away by just disabling robustBufferAccess and passing in everything
else supported as-is for vkCreateDevice.

Shawn Rutledge 64967461ee QVulkanWindow: fix fatal warning on Clang 4
qtbase/src/gui/vulkan/qvulkanwindow.cpp:1882:42: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
        VkClearColorValue clearColor = { 0.0f, 0.0f, 0.0f, 1.0f };
                                         ^~~~~~~~~~~~~~~~~~~~~~
                                         {                     }
1 error generated.

VkClearColorValue is a union, so it wants to be clear that we are
initializing only one of the union's members, apparently.
(Even though initing more than one wouldn't make sense.)

Martin Smith 6505062f58 doc: Fix several qdoc warnings in new software
This change fixes several common qdoc warnings in this new software.
However, because vulkan/vulkan.h is not always available, a few typedefs
were also added to define some standard vulkan types for clang to see
when vulkan.h is not available.

Laszlo Agocs dfef2e3f3e Clarify the front face winding order in the Vulkan examples
After applying the correction matrix the front face is CW, not CCW.

The examples work either way but fix them up to avoid reader confusion.

Laszlo Agocs 92dce210a2 QVulkanWindow: Add missing device wait after user code
In a multi-threaded setup it is not unlikely that
releaseSwapChainResources() will wait for and submit any remaining
frame building. Hence a wait is necessary also after invoking the user's
implementation.

Laszlo Agocs 8d72aba9e3 Introduce QVulkanWindow
A convenience subclass of QWindow that provides a Vulkan-capable
window with a double-buffered FIFO swapchain.

While advanced use cases are better served by a custom QWindow
subclass, many applications can benefit from having a convenient
helper that makes getting started easier.

Add also three examples of increasing complexity, and a variant that
shows embeddeding into widgets via QWindowContainer.

[ChangeLog][QtGui] Added QVulkanWindow, a convenience subclass of
QWindow.
