Lioncash f9c20571ab PostProcessing: Default constructor and destructor of PostProcessingShaderConfiguration
Also ensure that all members of the class are initialized on
construction as well. Previously the bool indicating if options are
dirty wouldn't be initialized, which could be read uninitialized if an
instance was constructed and then IsDirty() is called.
