Enum DisplayVisibleRegion 

pub enum DisplayVisibleRegion {
    Full,
    InscribedCircle,
}

The region of the surface the display physically shows. The renderer may refuse to shade anything outside it.

This is PLATFORM (or otherwise host-declared) truth about the display, never derived from app content — apps cannot invent one for their own scene; they get the cull for free on any layout.

Variants

Full

The whole surface is visible (every rectangular display). The cull machinery never engages: no depth attachment, no occluder, no pipeline variants — bitwise-identical rendering.

InscribedCircle

Only the circle inscribed in the surface rect is visible — the round-display panel shape (center at the surface midpoint, radius min(width, height) / 2).
