pub fn update_url_free_param(free_param: String)

pub fn update_url_param(key: String, value: String)

This does nothing on native. On web, it modifies the current URL to change the first named parameter in the HTTP GET params to the specified value, adding it if needed.

pub fn update_url_cam(ctx: &EventCtx<'_>, gps_bounds: &GPSBounds)

This does nothing on native. On web, it modifies the current URL to set –cam to an OSM-style zoom/lat/lon string (https://wiki.openstreetmap.org/wiki/Browsing#Other_URL_tricks) based on the current viewport.

pub fn change_camera(
    ctx: &mut EventCtx<'_>,
    raw: Option<&String>,
    gps_bounds: &GPSBounds
) -> bool

Parse an OSM-style zoom/lat/lon string (https://wiki.openstreetmap.org/wiki/Browsing#Other_URL_tricks), changing the canvas appropriately. Returns true upon success.

fn parse_center_camera(raw: &str, gps_bounds: &GPSBounds) -> Option<(Pt2D, f64)>

Parse an OSM-style zoom/lat/lon string (https://wiki.openstreetmap.org/wiki/Browsing#Other_URL_tricks), returning the map point to center on and the camera zoom.
