POLYGONTOROW Convert polygon coordinates to a row vector.

   ROW = polygonToRow(POLY);
   where POLY is a N-by-2 array of points representing vertices of the
   polygon, converts the vertex coordinates into a linear array:
   ROW = [X1 Y1 X2 Y2 .... XN YN]

   ROW = polygonToRow(POLY, TYPE);
   Can coose another format for converting polygon. Possibilities are:
   'interlaced' (default}, as described above
   'packed': ROW has format [X1 X2 ... XN Y1 Y2 ... YN].

   Example
   square = [10 10 ; 20 10 ; 20 20 ; 10 20];
   row = polygonToRow(square)
   row = 
       10   10   20   10   20   20   10   20 

   % the same with different ordering
   row = polygonToRow(square, 'packed')
   row = 
       10   20   20   10   10   10   20   20
