ehouse b0102f8baa Lots of progress on one-handed navigation: add gadgets to stand in for board
scoreboard and tray on palm; make center drill into the focussed object and
spacebar come back up then move the focus among them.  Integrate with other
focussable objects on main form.  Go from separate drawCursor routines to
same for all three, with cursor only visible when focus is drilled down.
On curses, add a hilite rect routine that can be called after text is laid
down, and use for cursors.
