  14  * 2     10/07/98 10:54a Dave
  15  * Initial checkin.

  17  * 1     10/07/98 10:51a Dave
  18  *
  19  * 10    4/12/98 5:31p Lawrance
  20  * use timer_get_milliseconds() instead of gettime()
  21  *
  22  * 9     4/02/98 5:27p John
  23  * Removed the mouse_count stuff that Hoffoss added.
  24  * Still some problems with mose_up_count being used twice, but that is
  25  * easily fixed.
  26  *
  27  * 8     4/02/98 5:05p Hoffoss
  28  * Fixed a timestamp() I missed.
  29  *
  30  * 7     4/02/98 10:04a Adam
  31  * Fixed UI mouse problems with buttons not registering correctly.
  32  *
  33  * 6     4/01/98 5:07p Hoffoss
  34  * Changed mouse button handling for UI in order to track fast events
  35  * (like button going down and released all between frames).
  36  *
  37  * 5     2/06/98 3:36p Hoffoss
  38  * Made disabled buttons play failed sound if clicked on.  This is now
  39  * standard behavior for all UI buttons everywhere.
  40  *
  41  * 4     1/14/98 6:44p Hoffoss
  42  * Massive changes to UI code.  A lot cleaner and better now.  Did all
  43  * this to get the new UI_DOT_SLIDER to work properly, which the old code
  44  * wasn't flexible enough to handle.
  45  *
  46  * 3     12/02/96 2:17p John
  47  * Made right button drag UI gadgets around and
  48  * Ctrl+Shift+Alt+F12 dumps out where they are.
  49  *
