-https://github.com/inuyaksa/jquery.nicescroll
-
-
-New features
-- scrolling with css transition (for full hw speed)
-- cssHook-ed scrollTop property, hw-scroll can be controlled by jQuery and you can use animation
-- override jQuery scrollTop function, hw-scroll can be controlled by jQuery and you can use animation
-- nicescroll object linked with jQuery DOM, using $.data named "__nicescroll"
-- jQuery function's getNiceScroll, to get the nicescroll object using $ selectors
-- only one instance for div, it checks if nicescroll already exists on the div
-- "grab" icon on div with touchbehavior = true
-
-New options
-- grabcursorenabled, display "grab" icon for div with touchbehavior = true, default is true
-- autohidemode, how hide the scrollbar works, true=default / "cursor" = only cursor hidden / false = do not hide
-- background, change css for rail background, default is ""
-
-Changed features
-- zIndex for scrollbar of document is the default value and for others is default+2
-- using css "background-clip" with value "padding-box" for a better cursor display. (see http://css-tricks.com/7423-transparent-borders-with-background-clip/)
-
-Fixes
-- zoom on iOS4, not fully visible
-- textarea resize bug, scrollbar didn't update
-- IE7, page scrollbar not hidden 
-- IE7-IE8, touchbehavior (grab-to-scroll) doesnt' work
-- IE8, workaround for IFRAME onload bug
-- Opera, key repetitions not working
-- scrollball don't update position when div has resized (no wrapper div), only for IE/Firefox/Opera
-
-
-Known issues
-- textarea on Firefox7, native scrollbars can't be hidden (firefox bug?)
-- chrome, -webkit-grab value accepted but cursor remain as pointer (possible browser bug)
-- chrome/safari, can't detect div resize (browser limitation)
