  * Button disabling (greying out)
  
  http://mke3.net/blender/interface/controls/greyed_out.png
  
  Another little intermediate addition, something that's been needed
  for a long, long, long time. Hopefully now, rather than a weird mix
  of buttons disappearing (or not) based on various conditions, this
  can be standardised on as much as possible. I don't know if this is
  the nicest way to do it, but I've tried to keep it fairly
  unobtrusive, and hey, it works.
  
  While disabled, the buttons are tinted roughly 50% against the
  background colour, and don't respond to any mouse-overs, clicks,
  or tabs.
  
  The code to use it is very simple, just like the button
  alignment code. Just surround the relevant button definitions with:
  uiBlockBeginDisabled(block, condition); and
  uiBlockEndDisabled(block);
  
  The 'condition' parameter is the condition under which the buttons
  are disabled, so if it evaluates, the buttons are disabled, if it
  equals 0, the buttons remain enabled as normal.
  
  Eg.
  
  uiBlockBeginDisabled(block, (!(ob->transflag & OB_DUPLIVERTS)));
   uiDefButC(block, TOG|BIT|5, REDRAWVIEW3D, "Rotation",   ...
  uiBlockEndDisabled(block);
  
  This can also be used in menus, I've already included one example
  usage in the 3D View -> View menu that disables the 'Camera' option
  if there is no active camera in the scene:
  
  http://mke3.net/blender/interface/controls/greyed_out_menu.png
  
  The code for this is:
  
  uiBlockBeginDisabled(block, (G.scene->camera == NULL) );
   -- code for the menu entry here --
  uiBlockEndDisabled(block);
  
  Anyone who would like to compile a list of places where this should
  be used throughout the menus/buttons is very welcome to do so, or
  even offer a patch :)
