Function SpatialMaterial.setFlag

If true, enables the specified flag. Flags are optional behaviour that can be turned on and off. Only one flag can be enabled at a time with this function, the flag enumerators cannot be bit-masked together to enable or disable multiple flags at once. Flags can also be enabled by setting the corresponding member to true. See flags enumerator for options.
