pub const LAYLINE_LENGTH_FACTOR: f64 = 1.3;Expand description
How far past the mark a layline ray reaches from layline_rays, as a
multiple of the vessel’s own current distance to the mark – long
enough that the ray always extends past wherever the vessel actually
is on the chart, short enough that it does not dominate a zoomed-in
view. A fixed on-screen length cannot do this: it would either vanish
at ocean scale or blot out a marina at pier scale. pub so every
client draws the same length rather than picking its own.
