The virtual scrollbar is for very large scroll area.
Browsers have issues with more than divs more than 6m pixels width/height (which by most account is reasonable).
This virtualScrollbar also has an elastic component that allows the scrollbar to shrink to its minSize
for easier scrolling for large virtual areas with small content areas. (Similar to excel desktop)
Note -
Because of the virtual nature of the scrollbar the onScroll method is disabled
and onScrollOffset must be used.
