- added 'flooralpha' and 'ceilingalpha' sector properties. They only have meaning if a sector stack portal is defined in this sector. If set to anything less than 1.0 these will override the alpha set by a portal. This is mostly for Sector_SetPortal to avoid defining multiple portals that only differ by their plane translucency.
