# default-features off so the renderer is an explicit choice below, never an
# accident: on a Pi 5 (Mesa V3D) the default FemtoVG renderer draws every runtime
# loaded Image as solid black - see slint-ui/slint#11785 - which for this app means
# every album cover. The `skia` feature is the device's way out.

default = ["desktop"]

# Development on a normal desktop session. FemtoVG is fine on x86/Mesa and builds in
# seconds, which is what makes it the right default *here* and the wrong one on the Pi.
# `renderer-software` rides along so `SLINT_BACKEND=winit-software` works without a
# rebuild: it is how the UI can be rendered and screenshotted on a machine with no GPU
# (or no session), and it is the fallback the Pi 5 FemtoVG bug leaves standing.
desktop = ["slint/backend-winit", "slint/renderer-femtovg", "slint/renderer-software"]

# Same window, Skia instead - the combination the device runs, so visual checks here
# match what ships. Costs a long first build while rust-skia bootstraps.
skia = ["slint/backend-winit", "slint/renderer-skia"]

# The device: straight onto KMS/DRM with no X, no Wayland and no compositor, input
# via libinput. (`backend-linuxkms-noseat` is deprecated upstream in favour of this.)
#
# Build it with `--no-default-features --features kiosk`: cargo features are additive,
# so leaving `desktop` enabled links winit and linuxkms into the same binary.

# The UI is laid out and hit-tested in debug builds too; an unoptimised image resize
