* Used now 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 neightbour 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 neightbour cells
|
|
* the previous cell on the same line and the previous cell on the same column.
|
|
*
|
|
* This funtion 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)
