[Gridflow-dev] multiblob for GridFlow

[Mathieu Bouchard]

Here's multiblob for GridFlow.

     http://gridflow.ca/gallery/multiblob.png

It's actually my own implementation: it's not been ported from anywhere 
else. Each cross is centered on the centroid (1st order moment) of its 
corresponding region ("blob"), and the size of the cross is the square 
root of the area of the region.

I will make another version which will use rotated rectangular crosses. 
The two lines of each cross will represent the two radiuses of the 
standard deviation of the region, and the angle will represent the angle 
of the standard deviation. I will use [#moment_polar], an abstraction 
based on [lti.Jacobi].
