* Function propagate
* Used only in autoplace calculations
* Uses the routing matrix to fill the cells within the zone
* Search and mark cells within the zone, and agree with DRC options.
* Requirements:
* Start from an initial point, to fill zone
* The zone must have no "copper island"
* Algorithm:
* If the current cell has a neighbor flagged as "cell in the zone", it
* become a cell in the zone
* The first point in the zone is the starting point
* 4 searches within the matrix are made:
* 1 - Left to right and top to bottom
* 2 - Right to left and top to bottom
* 3 - bottom to top and Right to left
* 4 - bottom to top and Left to right
* Given the current cell, for each search, we consider the 2 neighbor cells
* the previous cell on the same line and the previous cell on the same column.
*
* This function can request some iterations
* Iterations are made until no cell is added to the zone.
* @return added cells count (i.e. which the attribute CELL_IS_ZONE is set)
