The 3-arg QObject::connect() overload (the "contextless" one) simply
forwards to the 4-arg overload, using the sender object as both
the sender and the receiver/context.
QHostInfo does not use connect() directly in order to emit notifications
that a lookup is finished. Instead, it uses some of QObject private
plumbing. When handling a lookup request that specifies a function
to call when done, but no context object, QHostInfo passes nullptr
as context/receiver.
Change QHostInfoResult's behavior to always have a "receiver": in case
the caller didn't specify one, use `this` (= the sender).
As a drive-by, this allows to streamline some code.

Running the BenchmarkDemoQt6 application features a massive
startup time, followed by running out of memory (GPU-side,
assuming a discreet adapter), which is then remedied by the
system with heavy swapping. This is due to creating 8+ GB
of staging data.
While there are doubts about the application itself (seems there
is an upload for each Quick 3D Texture per material per model,
even though the texture itself is the same?), there is no reason
for the D3D12 backend to use so much more memory compared with
other backends.
That is now ensured by only creating a staging area for the data
(taking the 256-aligned row pitch requirement into account), not
simply using the subresource (i.e. the whole image) size. This is
equivalent to what e.g. the Vulkan backend does.

If an inline member function is defined outside of its class' body,
its declaration must have the inline keyword. Otherwise, in certain
situations, MinGW complains like this:
qstring.h:1118:13: error: 'void QString::clear()' redeclared without dllimport attribute after being referenced with dll linkage [-Werror]
Fix all instances in qstring.h by
- adding the inline keyword where it was missing on the definition
(except constexpr functions, which are implicitly inline)
- removing the inline keyword from all out-of-class-body definitions
While the latter isn't necessary for fixing the MinGW
warning-turned-error, the churn is warranted: It's enlisting all
platforms' help in checking for inline consistency (by causing
"multiple-definition errors" at link time or "inline function never
defined" at compile time when we get it wrong). If we kept the inline
keyword on the definitions, only MinGW would continue to warn, and only
in some, as of yet not fully understood, situations, so we'd have no
control over when these warnings pop up in user code.

With the referenced patch framebuffer invalidation is preferred
over clearing with a wider range of OpenGL implementations.
This is good and is in line with the documentation. If an existing
application does not do glClear() in their reimplemented paintGL(),
that we cannot fix, and the docs never actually promised that a
glClear() is done automatically.
However, there is a special case: when one does not reimplement
paintGL(). A QOpenGLWidget is expected to be usable without
reimplementing any of its virtuals (i.e., QOpenGLWidget is
constructible as-is without subclassing). It is then ideal
if this does not lead to showing rendering artifacts due to
having potentially random content in the (invalidated,
not cleared) color buffer. This problem was never encountered
before due to hitting the invalidate-instead-of-clear code path
on a limited set of platforms (like with OpenGL ES) only.
Do a glClear() in paintGL(). This won't effect the vast majority
of applications, that reimplement this function, but plays nice
for when it is not.
It is in fact also in line with Qt 4's QGLWidget: that also used to
do a glClear() in the default paintGL() implementation.

up until 6.4 uses Nearest, whereas the OpenGL -> QRhi migration
introduced using Linear in 6.4)
Meanwhile, the as of now undocumented high DPI downscaling feature
got introduced, and that prefers linear filtering. (since that's
definitely not a 1:1 mapping when it comes to texture size and the
on-screen quad) To reconcile the differences, add support for both
kind of samplers, and choose based on the sizes.
