Olive Vaughn 490460bf45 Drag timeline rows into symbols, into groups, and back out
A node's row can be dragged onto an instance's row, to go inside the symbol
it places; onto any other node's row, to be grouped with it into a new
symbol; or onto empty label space, to come back to the top of the open
symbol. All three keep the picture and the timing as they are, and a refused
move says why in the status line. Pool drop targets now only take things out
of the pool, and row drags set a move effect so the browser delivers the drop.
