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().

This builds on the mechanism that Albrecht added to test flipped and inverted image drawing, but allows the settings to be changed at runtime rather than at compile time as previously.
I'm commiting it here for testing use in the porting branch, but I'm not happy I've really tested it enough yet so reluctant to commit it in the main fltk-1.3.x branch until this code has been reviewed and tested by others.

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

File Fl_Image_Surface.cxx still needs to be cut in several platform-specific files.

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 defines additional preprocessor macros to enable testing
negative d and ld arguments of fl_draw_image(). Documentation (test
scenario) has also been improved.
Same commit as in branch-1.3, svn r11269.

Platform headers should not be #include'd in public FLTK header files,
so that user space is not polluted by platform specific definitions.

This commit fixes FL/fl_utf8.h to #include X11 headers only if compiled
in the FLTK library (same as in FLTK 1.3.4, svn r 11266).
Todo (FLTK 1.4): Remove more unnecessary (unwanted) system header #include
statements from FL/x.H and other public header files.

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.
