#turn off directional indicators if elevator is switching into a service mode, or is being switched off
#startup functions no longer crash if CreateElevator is never specified
#positioned elevator sounds properly
#need to initialize motor idle sound (fixes potential crashes)
#elevator door and chime sounds are now positioned properly at the door
#removed change_light parameter of AddRoute function, since the call type now handles this
#elevators now set queue-related call status for each call (car, hall and system), and they no longer chime if a related hall call is not active on that floor
#elevator queues can now store call-related information in addition to floor number
#(Glass Tower) added remaining interior atrium windows
#removed "SetUpIndicator" and "SetDownIndicator" buttons from elevator editor
#elevator door sensors are now set permanent to prevent crashes
#controls and triggers can now be made permanent
#AreDoorsMoving function now supports checking separate door types
#fixed an issue where the car idle (fan) sound would play when only shaft doors were opening
#elevator door name fixes
#door/sensor reset is now only done if doors are opened normally
#sensor and nudge modes are now switched off when manually opening doors
#for manual elevator doors, interlock error needs to reset direction value, otherwise a lockup may occur
#interior directional indicators are given the floor number to check for the existence of shaft doors
#elevator interior and exterior directional indicators are now controlled together from elevator's SetDirectionalIndicators function
#elevator should switch off directional indicators if leaving that floor
#added ShaftDoorsExist function to elevator
#added a shut-off timer to the directional indicator object, which will only start if associated elevator's AutoDoors is false, or no shaft doors exist on that floor
#rewrote ReplaceAll function, to work directly on the string reference to avoid copies
#in IfProc function, keep character references for performance
#optimization to the Cut function - only do name string copies when necessary
#sensor status variables need to be initialized first
#added more CS information to the texmap.cpp file
#GetPoint/isect functions are now working
#removed unnecessary vertex array copy from planar texture mapper
#wall object's plane calculations need to use full vertex list - this is the same issue as r3356

#fixed length values for a number of action names - fixes issues where door number parameters don't work
#fixed elevator's DoorsStopped function
#elevator will no longer move if doors are stopped and interlocks are enabled

#caller objects are now passed to actions when running
#cleaned up elevator number text code for reports
#elevator doors now report if no timer reset will be performed due to blocked sensor
#triggers can now report their "inside" status
#elevator doors no longer reset door timers if sensors are blocked/triggered
