Opt in via environment variables:
QSG_RHI=1 -> enable using QRhi instead of GL
QSG_RHI_BACKEND -> set to vulkan, metal, d3d11, gl to override the default
(the default is d3d11 on Windows, metal on Mac, gl elsewhere)
Or force a given rhi backend via the existing
QQuickWindow::setSceneGraphBackend().
Otherwise the default behavior is the same as before, the rhi code path
is never active by default.
-no-opengl builds are supported in the sense that they work and default
to the software backend. However, the rhi code path cannot currently be
used in such builds, even though QRhi from qtbase is fully functional
with Vulkan, D3D, or Metal even when qtbase was configured with
-no-opengl. This cannot be utilized by Quick atm due to OpenGL usage
being all over the place in the sources corresponding to the default
backend, and those host the rhi code path as well. This will be cleaned up
hopefully in Qt 6, with the removal all direct OpenGL usage.
Other env.vars.:
QSG_RHI_DEBUG_LAYER=1 -> enable D3D debug or Vulkan validation layer
(assuming the system is set up for this)
QSG_RHI_SHADEREFFECT_DEBUG=1 -> print stuff from ShaderEffect
QSG_SAMPLES=1,2,4,... -> MSAA sample count (but QSurfaceFormat works too)
QT_D3D_ADAPTER_INDEX=0,1,... -> D3D adapter index
QT_VK_PHYSICAL_DEVICE_INDEX=0,1,... -> Vulkan physical device index
QSG_RHI_UINT32_INDEX=1 -> always use uint index data (both
merged/unmerged, convert when needed - with some rhi backends this is
implicit)
QSG_RENDER_LOOP -> to override the render loop as usual. The default
with RHI is threaded for Metal, threaded for Vulkan on Windows, basic
for Vulkan on Linux and Android (to be checked later), while the existing
rules apply for OpenGL.
Not supported when running with QRhi:
- particles
- compressed atlases (though this is transparent to the apps)
- QSGRenderNode
- QQuickRenderControl
- QQuickFramebufferObject
- certain QQuickWindow functionality that depends directly on OpenGL
- anisotropic filtering for textures
- native text may lack some gamma correction
- QSGEngine applicability unclear
- some QML profiler logs may be incorrect or irrelevant

The qmlscene --resize-to-root feature has always been missing from
the qml runtime tool; however it was already possible to add it by
writing a custom configuration file. Now we support loading different
configurations from resources as well as from the filesystem, and
the first new configuration being added here is resizeToItem.qml
which provides behavior equivalent to qmlscene --resize-to-root.
When the argument given to --config ends with .qml, by convention
it's to be loaded from the filesystem; whereas configurations from
resources are specified without the .qml extension (to make the
command line shorter).
[ChangeLog][QtQml][qml] The QML Runtime tool now has default behavior
matching qmlscene when the root QML object is an Item: it will be
wrapped in a Window which will resize the Item when the Window is
resized. But you can alternatively use the --config resizeToItem
option, resulting in the same behavior as qmlscene --resizeToRoot:
resizing the root Item programmatically causes the wrapping Window to
be resized. Behavior can still be customized in other ways using the
--config option with an external QML configuration file.

QTranslator::install(QLocale, ...) indirectly uses
QLocale::uiLanguages(), which is the correct way to
ask the system for ui languages.
This was already attempted once in commit 427646b8d7,
but reverted later on in commit 05d8ffb4df, because
it requires shipping .qm files for the native language.
Anyhow, we're shipping empty Qt translations for English
since a while, and also have been fixing our examples
to do so.

QLocale::uiLanguages() for which the translation file is found.
That is a long list on OSX.
Reverting the patch means find_translation() is not called in
such cases. This change can be re-done whenever we are more sure
that the attempt to find a translation will succeed in finding a
sensible one, or fall back to not translating, rather than choosing
a language that the user didn't intend.

const QLocale& is better because it "uses QLocale::uiLanguages()
and not simply the locale name, which refers to the formatting of

a default-constructed QLocale permits QLocale::setDefault() to
override the system locale, so for example an application's
