Restore to site settings
ParaView's custom default settings feature supports resetting the custom default settings back to the original default values that ship with the binaries. However, for installations with custom defaults settings specified at the site or organizational level, it is more desirable to reset custom defaults back to the site setting values. If a site setting isn't available, we fall back to restoring to the application defaults.
This feature applies to all proxies. Transfer function proxies are handled specially to accommodate custom values for particular array names, but the general functionality is the same.
