* Function AddClearanceAreasPolygonsToPolysList
* Supports a min thickness area constraint.
* Add non copper areas polygons (pads and tracks with clearance)
* to the filled copper area found
* in BuildFilledPolysListData after calculating filled areas in a zone
* Non filled copper areas are pads and track and their clearance areas
* The filled copper area must be computed just before.
* BuildFilledPolysListData() call this function just after creating the
* filled copper area polygon (without clearance areas)
* to do that this function:
* 1 - Creates the main outline (zone outline) using a correction to shrink the resulting area
* with m_ZoneMinThickness/2 value.
* The result is areas with a margin of m_ZoneMinThickness/2
* When drawing outline with segments having a thickness of m_ZoneMinThickness, the
* outlines will match exactly the initial outlines
* 3 - Add all non filled areas (pads, tracks) in group B with a clearance of m_Clearance +
* m_ZoneMinThickness/2
* in a buffer
* - If Thermal shapes are wanted, add non filled area, in order to create these thermal shapes
* 4 - calculates the polygon A - B
* 5 - put resulting list of polygons (filled areas) in m_FilledPolysList
* This zone contains pads with the same net.
* 6 - Remove insulated copper islands
* 7 - If Thermal shapes are wanted, remove unconnected stubs in thermal shapes:
* creates a buffer of polygons corresponding to stubs to remove
* sub them to the filled areas.
* Remove new insulated copper islands
