//! The position indicator shows the mouse position on the map
//!
//! The exact position the mouse is currently on is shown unless hidden by the user (TODO). This
//! helps to place things exactly where they should be on the map and let the user know where they
//! are looking and where relative to them other things should be easily at all times. Currently, this
//! is a simple HUD so it doesn't interact with anything in the world, but that may change in the
//! future.
