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.
+The alignment field specifies how the item will be aligned. It ranges from -1 to 1,

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