+--[[ 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.
