Detailed Description

Integer min and max, a packet-release helper, and the single-precision angular constants.

Address range 41d0c0-41d11f. MinShort and MaxShort have 94 call sites across the game core. The constants' read-only data follows the barracks menu regions and precedes the DirectDraw GUIDs, as only a unit linked between those two can place it.
