It is necessary to have a stack of the fl_begin_offscreen() calls, so that nested
such calls apply fl_end_offscreen() to the matching fl_begin_offscreen().

The Xlib driver is tricky because it uses two kinds of offscreen buffers.

This commit fixes a regression in FLTK 1.3.x, where negative values
of 'd' (pixel delta) and 'ld' (line delta) didn't work anymore under
Unix/Linux (X11) and Windows.
With this commit the regression is fixed on all supported platforms.
Equivalent of branch-1.3, svn r11270.

This commit adds the basic setup in CMake to allow SDL as a base
library for FLTK on OS X (and probably for other platforms as well).
The SDL library driver set is derived from yet another new driver
set named 'Pico'. 'Pico' is a base class for a driver that will
allow porting of FLTK with the tinyest amount of effort. This
implementation of the SDL driver shall be documented very well
to explain the porting process.

This change requires other changes in header inclusions by class Fl_Image_Surface.

This commit includes all fixes from branch-1.3 (svn r 11243) and additional
fixes for warnings that crept in during the porting efforts, particularly
C++ ("//") comments in C and included header files, and some more.

These functions become therefore platform-independent.

This simplifies the implementation of Fl_Copy_Surface and Fl_Image_Surface
which now are made to derive from Fl_Widget_Surface.

It is not possible to use fl_graphics_driver in these functions
because when they are called *fl_graphics_driver may have been
deleted. A solution is to use Fl_Display_Device::display_device()->driver()
instead which is always valid.

Note: ../../config_lib.h also includes <config.h>.

Some refactoring of a take_focus() function into driver structures (not too happy with it, because it has some kind of bug fix. However, shouldn't *all* Fl_Windows always have an FL_Window_Driver?)

Adding two new driver types for each platform. Fl_..._System_Drivers exist once per application and provide an interface for to file and filename handling, timers, locking, multithreading, etc. .
The Fl_..._Window_Driver class is instantiated once for every window in the system and corresponds closely to (and actually inherits from) Fl_X. The difference now is, that there is one Fl_X/Fl_Window_Driver base class, and one platform version that derives from it.

fl_gc remains usable by the application as a hook into the system.
