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.

The first deploy to the Steam Frame aborted in install.sh: OVRAS creates
its QApplication before it handles --force-install-manifest, and Qt's
default platform plugin (xcb) aborts when there is no display, as over
SSH. Registering and unregistering draw nothing, so the generated
install.sh and uninstall.sh now run them with QT_QPA_PLATFORM=offscreen.
The normal start keeps DISPLAY=:0, as rendering needs a real context.

- 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/.
