function argument cleanup

fix for cppcheck funcArgOrderDifferent
> Function 'SearchRow' argument order different:
> declaration 'nRow, nRight, nLeft, nPref, bRight, bSimple'
> definition 'nRow, nLeft, nRight, , bRight, bSimple'

remove unused nPref argument
swap arguments where nTop was obviously bigger than
nBottom or nLeft bigger than nRight
use std::swap

no logic change intended
