[flexcoders] Reduce the height of sortItemRenderer ( AdvancedDataGridHeaderRenderer )

[Vijay Anand Mareddy]

I extended the AdvDataGridHeaderRenderer and added a TextInput for 
displaying column totals.
All is fine except that i want my TextInput to occupy the complete 
column width (=100%) and push the sortItemRenderer down.
Any comments anybody?
