#labeling gives you the area of each blob, the centre position of each 
blob, the variance of each blob (in xx, yy, and xy), and also it 
floodfills every blob in the original picture using a different "colour" 
(number). this is the default mode.

the other mode of [#labeling] treats each scanline as a different picture 
with its own blobs, and outputs the blobs as a sequence of 2-vertex 
"polygons".
