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.

These functions become therefore platform-independent.

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

Searching for __APPLE, WIN32 or X11 did give me many false results. I instead marked most ifdef's that I would like to get rid of with the text // PORTME:, so they can be easily found by a global search.

- Moving code around for Fl_Double_Window, but not yet happy
- Tested CMake for Android cross compilation. Very happy!

During the last refactoring on OS X, a few thing were relocated into new files, mainly to avoid ifdef's and use C++ inheritance in a driver system instead. This commit makes FLTK compile again under VC2013 with IDE files generated by CMake.

- The previous check-in for OS X moved a few files and symbols around
- Fixing for Linux what I broke in my previous commit
- Fixing stuff for MSWindows next
- CodeBlocks IDE file generation via CMake works

and whether we are printing: virtual int Fl_Graphics_Driver::has_feature(driver_feature feature)
This is also because it is not convenient to derive a printer-specific driver with its own
implementation of virtual functions when this implementation differs only in one line of code.
2) Solved the problem of inclusion of non public header by the public header FL/Fl_Device.H:
bracket this with #if FL_LIBRARY / #endif so this non public header is included only when building
FLTK itself.
3) Removed several (but not all) of the FLTK_ABI_VERSION guards that are no longer
useful for code targeting FLTK 1.4.

graphics context to draw to a window. This requires Mac OS 10.4.
The advantage is that it is possible for a secondary thread to call
Fl_Window::make_current() without needing to create an autorelease pool.
We save the native graphics state, and also the state with origin at top.
Fl_X::q_release_context() restores the graphics state twice to return to
the native state. This allows to use a single graphics context for a single
window and a single thread.
Under 10.3, we have to create a new NSGraphicsContext when Fl_Window::make_current()
is called directly, so that secondary threads cannot call Fl_Window::make_current() without
having created an autorelease pool.

The fix is twofold:
(1) if Fl_Window::flush() is called, this is ignored silently
(2) if Fl_Window::make_current() is called directly, but the window
is currently not shown(), then the program will be terminated
with an error message.
The latter is necessary because returning from make_current() would
leave the program in a state where it would expect to have a valid
drawing context.

Thanks to Mathieu Peyrega for the patch in fltk.general [1] on Nov 14, 2011,
although I implemented it differently.

in FLTK 1.1).
src/Fl_Double_Window.cxx/Fl_Double_Window::resize():
STR #2152: deallocate back buffer when window is enlarged in any
dimension to force allocation of a new back buffer. This appears
to be necessary for some window managers (e.g. Cygwin).
src/Fl_Overlay_Window.cxx/Fl_Overlay_Window::flush() and
src/Fl_Double_Window.cxx/Fl_Double_Window::flush():
STR #2197: make sure that the entire overlay window will be drawn
after a window redraw, because Fl_Double_Window::flush(1) erases
the overlay as documented.
