				* Individual filter parameters are ORed with the asset properties. That means:
				* * The asset type must be one of the ID types filtered by, and
				* * The asset must contain at least one of the tags filtered by.
				* However for an asset to be matching it must have one match in each of the parameters. I.e. one

				* \returns True if the asset should be visible with these filter settings (parameters match).
