This code is not very beautiful, but the resulting class should be
easy to use. A range-based loop can be used to find all relevant
clipping rectangles for a drawing call.

Make clipping methods non-virtual so they can be inlined.

fl_rectf is so far the only function that uses the complex clipping
region successfully. Code is slow, but works.

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.

Back to 16-bit coordinate limit clipping (actually +/- (2**15 - 8).
The clipping range is now constant, symmetrical, and stored in the
driver object.
Also fixed a bug in Liang-Barsky line clipping algorithm.

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.

Note: These two functions are not yet UTF-8 aware. Results may be unexpected.
Possible test case: run test/file_chooser or any FLTK program with
Fl_File_Chooser. The default display order is determined by fl_numericsort():
Fl_File_Chooser::sort = fl_numericsort;

Android has no classic window manager, so FLTK has to
make sure that popup windows, dialog boxes and multi
window interfaces work as expectd.

This member function transforms the current clip region from FLTK units to pixel units
multiplying FLTK units by the current value of the scale factor to get pixel units.
The current clip region has been, by construction, restricted to the 16-bit coordinate space.
But these data can evade this space after multiplication by the scale factor.
Thus, it's necessary to enforce the 16-bit space here which is done with Fl_Xlib_Graphics_Driver::XRectangleRegion.

In FLTK 1.3.x only horizontal and vertical long lines with endpoints
outside the 16-bit coordinate space could be drawn with proper X11
coordinate clipping. Now arbitrary lines are clipped so they can be
drawn with X11 functions.
All rectangles are clipped as well (as in 1.3).
Todo: The code needs better documentation and clipping of polygons,
circles, curves etc. is still missing. The next step should be the
clipping of polygons...

At this point, Windows FLTK apps detect HighDPI displays and rescale their GUI accordingly. They also
all reply to ctrl/+/-/0/ keystrokes to enlarge/shrink/reset their windows.

This is the first commit of X11 16-bit coordinate space (clipping) fixes.
More to follow...
