  33  * 10    4/12/98 5:31p Lawrance
  34  * use timer_get_milliseconds() instead of gettime()
  35  *
  36  * 9     4/02/98 5:27p John
  37  * Removed the mouse_count stuff that Hoffoss added.
  38  * Still some problems with mose_up_count being used twice, but that is
  39  * easily fixed.
  40  *
  41  * 8     4/02/98 5:05p Hoffoss
  42  * Fixed a timestamp() I missed.
  43  *
  44  * 7     4/02/98 10:04a Adam
  45  * Fixed UI mouse problems with buttons not registering correctly.
  46  *
  47  * 6     4/01/98 5:07p Hoffoss
  48  * Changed mouse button handling for UI in order to track fast events
  49  * (like button going down and released all between frames).
  50  *
  51  * 5     2/06/98 3:36p Hoffoss
  52  * Made disabled buttons play failed sound if clicked on.  This is now
  53  * standard behavior for all UI buttons everywhere.
  54  *
  55  * 4     1/14/98 6:44p Hoffoss
  56  * Massive changes to UI code.  A lot cleaner and better now.  Did all
  57  * this to get the new UI_DOT_SLIDER to work properly, which the old code
  58  * wasn't flexible enough to handle.
  59  *
  60  * 3     12/02/96 2:17p John
  61  * Made right button drag UI gadgets around and
  62  * Ctrl+Shift+Alt+F12 dumps out where they are.
