Function stripes_held_still 

pub fn stripes_held_still(
    stripes: &[StripeState],
    settings: &RustCaptureSettings,
) -> bool

Whether a frame that holds still codes a stripe at the paint-over quality instead of the session’s (encode_cpu): at a constant quality, a stripe whose cleanup falls due, whose burst is held, or which keeps the quality it was cleaned up at. A constant rate holds none there.
