Subject: [PATCH] Rework how progressbars are managed so you can have as many
 bars in a viewport as you want (!). Change %pv (volume) to be able to be
 drawn in the same style as %pb (using a line or a bmp). %pv - no change,
 %pv|bmp|x|y|width|height| exactly like %pb DO NOT use %?pv|....| because it
 will draw when you dont want it to!
