This was needed because Fl_X only exists if a window is mapped, but we need the driver from the very beginning. Adding Fl_X in the ctor would create hidden bugs. Strategy is now to remove system specific stuff from Fl_X and move it one-by-one to Fl_Window_Driver while maintaining a working code base. X11 and WIN32 fixups will follow in 15 minutes.

Fixed some issues with Image_Surface and Copy_Surface for PicoSDL. Still have to virtualize the driver concept.

Renaming the files will keep the namespace clean if we decide to do a full blown SDL port one day.
PicoSDL OTOH is merely there to explain how a Pico driver setup is started and improved.

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>.
