Description

Adds Wwise Spatial Audio portals. AudPortal wraps AK::SpatialAudio::SetPortal and is placed through ITr2BoxVolume, the same way as AudRoom, so trinity and the API need no changes. Rooms without portals are sealed; portals connect them, e.g. a door between two rooms.

Changes

• AudPortal, sent to Wwise by AudRoomManager
• Front and back rooms found automatically from the room boxes, a quarter of the portal's depth past each face, so a portal as deep as its wall still finds both rooms
• New rooms must be found 3 updates in a row before they replace the portal's rooms in Wwise, so the moving origin doesn't make them flicker
• Portals removed before the rooms they connect
• Door obstruction and occlusion (SetPortalObstructionAndOcclusion) and adjacent room bleed
• AudUnitBox, the box handling now shared by rooms and portals

Testing

• Tested locally with the same tool as the rooms PR, which will be released in a future PR.
