SYNOPSIS:
    MARKCC_CONNECTED_VIS x y z targetset [sourceset] [maxsteps]

DESCRIPTION:
    Fill the connected area starting at x,y,z. If no sourceset is
    given, or it is empty, use the class of the voxel at x/y/z.
    All voxels belonging to sourceset that are connected to x,y,z
    are remarked to targetset.
    If maxsteps is given, the flooding is stopped after this number
    of steps.
    The difference to MARKCC_CONNECTED is, that progress is displayed
    after every round, which allows for interactive control but may
    be slow if used on slowly-updating views.
