Crate fluor 

Fluor — first-principles GUI compositor library.

Center-origin, harmonic-mean RU coordinates with +y down and Spirix ScalarF4E4 storage. CPU pixel buffer with SIMD blits. Layout state serializes via VSF. Targets: aarch64 (production, including ferros bare-metal), x86_64 (development).

Modules

coord

Center-origin, +y-down 2D coordinates in f32.

geom

Viewport geometry: pixel dimensions, derived universal scaling units, and conversions between RU coordinates and integer pixel coordinates.

host

Host backends — adapters between fluor’s Compositor and the platform’s window/framebuffer system.

paint

Pixel-buffer paint primitives. ARGB layout is 0xAARRGGBB (alpha high byte, blue low). All inputs are pixel-space, not RU — convert via Viewport::ru_to_px before calling.

pane

Panes — the unit of UI in fluor — and the Compositor that owns them.

theme

Theme constants — colors and geometry shared between paint primitives, chrome, and (eventually) widgets. Sourced verbatim from photon’s theme.rs; names match photon exactly so cross-codebase greps work.
