To account for differing resolutions, the position coordinates are the percentage of the screen,

The name field is not yet used, but should contain a description of what the HUD element represents.
+The direction field is the direction in which something is drawn.

Below are the specific uses for fields in each type; fields not listed for that type are ignored.
