/**
 * Function ComputeRawFilledAreas
 * 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
