 * use timer_get_milliseconds() instead of gettime()
 * 
 * 9     4/02/98 5:27p John
 * Removed the mouse_count stuff that Hoffoss added.
 * Still some problems with mose_up_count being used twice, but that is
 * easily fixed.

 * 8     4/02/98 5:05p Hoffoss
 * Fixed a timestamp() I missed.

 * Fixed UI mouse problems with buttons not registering correctly.
 * 
 * 6     4/01/98 5:07p Hoffoss
 * Changed mouse button handling for UI in order to track fast events
 * (like button going down and released all between frames).
 * 
 * 5     2/06/98 3:36p Hoffoss
 * Made disabled buttons play failed sound if clicked on.  This is now
 * standard behavior for all UI buttons everywhere.
 * 
 * 4     1/14/98 6:44p Hoffoss
 * Massive changes to UI code.  A lot cleaner and better now.  Did all
 * this to get the new UI_DOT_SLIDER to work properly, which the old code
 * wasn't flexible enough to handle.
 * 
 * 3     12/02/96 2:17p John
 * Made right button drag UI gadgets around and
 * Ctrl+Shift+Alt+F12 dumps out where they are.
