void	autoscroll(java.awt.Point cursorLocn) Implements autoscrolling.
void	changeSelection(int rowIndex, int columnIndex, boolean toggle, boolean extend) Drag and drop is kind of weird in that when you drag something, you often start in a cell that has a component in it but by the time the drag handling code get's the event the selection has moved into a cell that does have a component in it and the drag fails.
