This allows users to request queues beyond the default graphics queue without having
to completely reimplement Vulkan device initialization or giving up the convenience
of QVulkanWindow.
[ChangeLog][QtGui] Extended QVulkanWindow to allow user to specify additional queues
to be created.

We need to override this snippet for the documentation
we generate for Qt for Python, and it is easier to have
it on a separate file.

Stencil is - very likely - cleared just like depth. Also, switch to
STORE_OP_STORE for the multisample buffer, for correctness.

Running with QT_VK_FORCE_STAGE_TEX does not work at all with recent
NVIDIA drivers due to QVulkanWindow's and the example's naive way of
picking the memory index. Enhance this and add a warning note to the
QVulkanWindow docs as well.

Applying the transformation in question has no effect on the winding
order. Rewrite that section.
While all the examples are correct, clarify the rules for the geometry
they use since the winding order varies. Fix up the triangle example code
to use front=CCW for clarity (even though it does not matter much since
culling is off there).

Apart from being more efficient to construct and test, for the
expected very small number of entries, the example code itself shows
that a sorted vector is much more useful than an unordered set.

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.)

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.

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

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.
