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

ranging in value from 0 to 1.
|

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.
|

0 draws from left to right, 1 draws from right to left, 2 draws from top to bottom, and 3 draws from bottom to top.

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