Enemy edge arrows no longer cover descent panels

The enemy edge arrows on the Shattered Rift HUD now stay clear of the surface approach, descent and ground-contact panels. The arrows keep their target, edge and bearing, and the limits on how many nearest threats are shown stay the same. The first screenshot is from combat after the change. The others show the old overlap and the corrected placement. We checked the HUD at five screen resolutions. This is a limited readability fix. Wider art, motion and performance work is still open.
