Struct widgetry::mapspace::DrawUnzoomedShapes

pub struct DrawUnzoomedShapes {
    lines: Vec<UnzoomedLine>,
    circles: Vec<UnzoomedCircle>,
    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

lines: Vec<UnzoomedLine>

circles: Vec<UnzoomedCircle>

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