Struct widgetry::mapspace::DrawUnzoomedShapes

pub struct DrawUnzoomedShapes {
    shapes: Vec<Shape>,
    per_zoom: RefCell<[Option<Drawable>; 11]>,
}

Draw Circles and PolyLines in map-space that scale their size as the canvas is zoomed. The goal is to appear with roughly constant screen-space size, but for the moment, this is approximated by discretizing into 10 buckets. The scaling only happens when the canvas is zoomed out less than a value of 1.0.

Fields

shapes: Vec<Shape>

per_zoom: RefCell<[Option<Drawable>; 11]>
