Changing cursor using DECSCUSR should immediately redraw and show the new cursor

I really like the new feature for changing the cursor via the DECSCUSR code, but I would like to suggest one improvement. I think when the cursor is changed to a vertical bar, block or underline it should redraw immediately and then follow the blinking schedule of everything else on the screen.
