--[[ Element: Resting Icon

 Toggles visibility of the resting icon.

 Widget

 Resting - Any UI widget.

 Notes

 The default resting icon will be used if the UI widget is a texture and doesn't
 have a texture or color defined.

 Examples

   -- Position and size
   local Resting = self:CreateTexture(nil, 'OVERLAY')
   Resting:SetSize(16, 16)
   Resting:SetPoint('TOPLEFT', self)
   
   -- Register it with oUF
   self.Resting = Resting

 Hooks

 Override(self) - Used to completely override the internal update function.
                  Removing the table key entry will make the element fall-back
                  to its internal function again.
