Function rise_from_foot 

pub fn rise_from_foot(
    layout: &mut ModalLayout,
    content_h: f64,
    grip: f64,
) -> bool

Raise layout, a compact window’s full-window page, as a sheet from the window’s foot that is as tall as what it holds: content_h of body, the title above it, the footer below it and a grip grip tall along its top. A form of a few fields asks from the foot, where the thumb is; one too tall for most of the window stays the whole page. Whether it rose.
