+ \brief Tests on the Watershed Transform (WST) on an artificial
+ mln::line_graph_image.
+
+ The scenario is as follows:
+ \li create an artificial (checkboard) 2-D image ;
+ \li convert this 2-D image into a line graph-based one, where values
+ on edges are computed as the absolute value of the difference
+ between the values on the vertices adjacent to the edge, so as to
+ create a (norm of the) gradient ``between the pixels'' of the
+ input image;
+ \li perform a WST on this line graph image;
+ \li create a 2-D, color output image with height and width double
+ the size the original one, and copy the data of the input image
+ in it, interpolating inter-pixel points;
+ \li print the watershed on lines into that same image, and save it. */
