Title: Examples/extruded text

The addContour method gets a bool parameter named hole. Main problem is to determine the holes and pass that parameter true. The code groups outlines of every character, order them by area (the one with max area is considered the out most) and then if the outline is not the last one and it is inside the last one the outline is considered a hole.
