+ * Compare \a asset against the settings of \a filter.
+ *
+ * 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
+ * matching type __and__ at least one matching tag.
+ *
+ * \returns True if the asset should be visible with these filter settings (parameters match).
+ *          Otherwise returns false (mismatch).
