 /**
  * @class Ext.grid.plugin.HeaderResizer
  * @extends Ext.util.Observable
- * 
+ *
  * Plugin to add header resizing functionality to a HeaderContainer.
  * Always resizing header to the left of the splitter you are resizing.
- * 
- * Todo: Consider RTL support, columns would always calculate to the right of
- *    the splitter instead of to the left.
