    height: u32,
    clear: Color,
) -> Option<OffscreenFrame>
Expand description

Renders scene into a width×height texture cleared to clear, then reads the pixels back. None when no GPU adapter is available — a machine with neither GPU nor software rasteriser — in which case test callers skip themselves.
