We need to change the result of REQUEST_IS_TWO_PANELS when the
flag is on because now we don't have two panels only 1.
Another of the issues is a rounding error when calling
getUnusedHorizontalSpace().
And lastly updating workspaceToBoards so that it maps the coordinate
of workspace items to their right position.
