When creating a drawable undo from the drawable's buffer, align the
copied rectangle to the buffer's tile grid, so that all the copied
tiles are COWed, saving memory and gaining speed.
Add applied_x and applied_y fields to GimpDrawableUndo, specifying
the position at which to apply the applied_buffer, so that we apply
it in the right place, even if the undo rect has changed due to
alignment.
