Clipping areas are calculated for overlapping windows, named "Desktop
Windows". The first level implementation works if the resulting complex
region is just a rectangle. Higher complexity (sub-rectangles) is next.

Complex clipping is needed to allow popup dialogs and menu window while
still correctly rendering windows that are "below" those popups.

improved Fl_Rect_Region class instead of Fl_Rect. Commented out
complex clipping.
Android lib and apps now use C++11 because they can (and I like it).

Also, added rectangular clipping which works.
Expanding now to a more complex clipping scheme to make multiple
windows work.
