		// Icons can be configured in code or automatically configured by an external file "drivername\resources\driver.vrresources".
		// Icon properties NOT configured in code (post Activate) are then auto-configured by the optional presence of a driver's "drivername\resources\driver.vrresources".
		// In this manner a driver can configure their icons in a flexible data driven fashion by using an external file.
		//
		// The structure of the driver.vrresources file allows a driver to specialize their icons based on their HW.
		// Keys matching the value in "Prop_ModelNumber_String" are considered first, since the driver may have model specific icons.
		// An absence of a matching "Prop_ModelNumber_String" then considers the ETrackedDeviceClass ("HMD", "Controller", "GenericTracker", "TrackingReference")
		// since the driver may have specialized icons based on those device class names.
		//
		// An absence of either then falls back to the "system.vrresources" where generic device class icons are then supplied.
		//
		// Please refer to "bin\drivers\sample\resources\driver.vrresources" which contains this sample configuration.
		//
		// "Alias" is a reserved key and specifies chaining to another json block.
		//
		// In this sample configuration file (overly complex FOR EXAMPLE PURPOSES ONLY)....
		//
		// "Model-v2.0" chains through the alias to "Model-v1.0" which chains through the alias to "Model-v Defaults".
		//
		// Keys NOT found in "Model-v2.0" would then chase through the "Alias" to be resolved in "Model-v1.0" and either resolve their or continue through the alias.
		// Thus "Prop_NamedIconPathDeviceAlertLow_String" in each model's block represent a specialization specific for that "model".
		// Keys in "Model-v Defaults" are an example of mapping to the same states, and here all map to "Prop_NamedIconPathDeviceOff_String".
