+ * The buffering_level functions here return a value in a normalized range
+ * that specifies the current fill level of a queue. The range goes from 0 to
+ * MAX_BUFFERING_LEVEL. The low/high watermarks also use this same range.
+ *
+ * This is not to be confused with the buffering_percent value, which is
+ * a *relative* quantity - relative to the low/high watermarks.
+ * buffering_percent = 0% means overall buffering_level is at the low watermark.
+ * buffering_percent = 100% means overall buffering_level is at the high watermark.
+ * buffering_percent is used for determining if the fill level has reached
+ * the high watermark, and for producing BUFFERING messages. This value
+ * always uses a 0..100 range (since it is a percentage).
+ *
+ * To avoid future confusions, whenever "buffering level" is mentioned, it
+ * refers to the absolute level which is in the 0..MAX_BUFFERING_LEVEL
+ * range. Whenever "buffering_percent" is mentioned, it refers to the
+ * percentage value that is relative to the low/high watermark. */
