On the Steam Frame, the fixed 1200x800 layout lost about its bottom
quarter. Measured with --snapshot: fonts and DPI are as intended, but
the controls ran in the Material style. The qt6 branch changed
mainwidget.qml's "import QtQuick.Controls" into
"import QtQuick.Controls.Material", which fixes Material for all
controls and even overrides QT_QUICK_CONTROLS_STYLE. Material's insets
and padding make the navigation buttons 65 px tall instead of 45 px
(Fusion) or 49 px (Basic, Qt 5's default style renamed); nothing in the
file uses Material.
mainwidget.qml imports QtQuick.Controls again, and main.cpp sets Fusion
explicitly, so the sizes are the same on every platform instead of
depending on Qt 6's per-platform default. With Basic the last navigation
button is still cut off on the Frame; with Fusion everything fits.

On the Steam Frame, the fixed 1200x800 QML layout overflows: about the
bottom quarter is cut off and the navigation icons overlap their text.
Forcing 96 DPI and switching the Quick Controls style didn't help, so the
cause has to be measured rather than guessed.
- SetWidget() logs the application font (family, pt, px), what 20 pt
(MyText) is in px, the screen's DPI and the device pixel ratio.
- --snapshot <file> writes the rendered overlay (RenderBackend::readback)
as PNG at most once per second while it is visible. A time interval,
because OVRAS only renders when the scene changes. Written to a
temporary file and renamed, so readers never see a partial file.
- run.sh passes arguments after the graphics API to the program.

Steam writes every VR app the user owns into its generated
steamapps.vrmanifest, installed or not. Whoever owns OVRAS on Steam
therefore always has steam.overlay.1009850 registered, as a steam:// URL
without a working directory, and --force-install-manifest failed with
"Could not find working directory of already installed application:
VRApplicationError_PropertyNotSet" (found on the Steam Frame).
Such an entry has no manifest file to remove, so OVRAS now leaves it
alone and adds its own manifest. Whether SteamVR accepts a second
manifest for the key, and which entry it then uses, is not documented:
logApplicationEntry() logs what SteamVR reports for the key after
installing, so a test on the Frame shows it.

- build_scripts/steamframe/: Debian trixie (Qt 6.8) containers for the
aarch64 cross build, native build and tests; toolchain; scripts to build,
test (Vulkan validation layers), package (system Qt, ~3 MB) and deploy over
SSH. Adapted from the vrdashboard template.
- test/render/: render test for the OpenGL and Vulkan backends, driven like
OverlayController (option OVRAS_BUILD_TESTS).
- RPATH only $ORIGIN, without the build machine's link directories.
- Ignore dist/.

Internal fork based on upstream's qt6 branch (2d4db7e). Goal: OVRAS runs
natively on the Steam Frame (SteamOS, aarch64) with a minimal change set
against qt6 and only public Qt API.
