The alignment field specifies how the item will be aligned. It ranges from -1 to 1,
with 0 being the center, -1 is moved to the left/up, and 1 is to the right/down. Fractional
values can be used.
+The offset field specifies a pixel offset from the position. Contrary to position,
+the offset is not scaled to screen size. This allows for some precisely-positioned

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