-/**
- The Fl_Complex_Region represents a clipping region of any shape.
-
- This class is organized in a tree-like structure. If the region is
- rectangular, is_simple() returns 1 and the rectangle can be used just
- as in Fl_Rect_Region.
-
- If a more complex representation is needed, subregions are created which are
- guaranteed to lie within the bounding box of the current region. Subregions
- themselves can again contain sub-subregions to describe the entire clipping
- region, effectively creating a tree where the leafs contain the rectangles
- that together describe the clipping area.
-
- To make life easier, Fl_Complex_Region provides two types of iterator to
- travers the entire tree.
-
- 1. Fl_Complex_Region itself is compatible to C++11 range-based loops and
-    can bewalked simply by writing ``for (auto &&it: rgn) { ... }``.
-
- 2. Fl_Complex_Region provides an alternative iterator that loop only through
-    leafs that intersects with a given rectangle. The returned object
-    provides access to the readily clipped rectangle.
-
- \code
- Fl_Complex_Region rgn(something);
- for (auto &&it: rgn.iterate(Fl_Rect_Region(0, 0, 100, 100)) {
-    draw_something(it->rect());
- }
- \endcode
