[Identifier] viewLimitTiltmin viewLimitTiltMax [Range / Default Value] -90.0 ... +90.0 [Description] 
Border values of the allowed tilting area, in degrees. Setting both limits to the same value effectively disables tilt limits. Note that cylindrical panoramas implicitely define tilt limits that can not be overriden. Special rules apply for equitectangular panoramas. With tilt limits disabled (e.g., both variables set to 0.0), the view center is restricted to the -90...90 tilt range. With differing min/max values for tilt, these limits apply the view border, instead.
