After experimenting with a modified cairo_test program that draws both with
cairo and with regular FLTK drawing functions to the same window, it seems
necessary to control for possible changes to the graphics context made by
cairo in Fl_Cocoa_Window_Driver::make_current() rather than in
cairo_create_surface().

Discussion "Screen buffer flipped in OSX Mojave running 1.4.x"
in fltk.general,
http://www.fltk.org/newsgroups.php?s36913+gfltk.general+v36915
describes a Cairo-using FLTK app that runs well after this modification.

The original intention of FL_PORTING was to mark all places in the
source code where changes are required to port FLTK to a new platform.
Thanks to the driver system, this approach has become somewhat
misleading, so I removed all references.

Replace compiler/preprocessor/platform macro "WIN32" with "_WIN32".
Replace "WIN32" in text and documentation with "Windows".
Replace "MSWindows" with "Windows".
To do: README.Windows.txt (and maybe other documentation as well)
needs updates.

This second step replaces FL/x.H with FL/platform.H in all source files.
Dependencies have been adjusted as well.
This commit completes the replacement of FL/x.H with FL/platform.H.

To use Fl_Cairo_Window one did not only need to configure with --enable-cairo,
but also needed to #include <config.h> before #include <FL/Fl.H>.
This commit removes the smaller part of the dependency of the public header
file FL/Fl.H on config.h. This needs a better solution in FLTK 1.4.0.
The user still needs to define FLTK_HAVE_CAIRO _before_ #include <FL/Fl.H>.
Note: This is not compatible with fluid, since fluid _always_ includes
FL/Fl.H as the first statement in generated header files.

configure is used to set all needed version numbers in makeinclude.
makeinclude is included in Makefile's and the version numbers are used
to build the correct shared libs.

All fluid .fl files have been rewritten with fluid 1.3.3 and may differ
somehow, but there are no significant changes.

than what we had previously, but may need some more testing. The latest
changes (removing old APPLE_QD definitions and code) might need another
update.

src/Makefile: adjusted WIN32 and Mac dependencies
test/Makefile: dto.
Todo: src/xutf8/makedepend needs to be checked. There are obviously functions
and headers that are included in a platform dependent way.

+ added new USE_CAIRO config preprocessor def.
to differentiate from HAVE_CAIRO so that we can use the cairo lib
without forcing the full fltk lib to be linked against it.
In that case, cairo autolink context functionality which needs fltk lib
instrumentation is disabled.
+ added new --enable-cairoext, which correspond to previous --enable-cairo.
now, --enable-cairo only adds HAVE_CAIRO def. and keeps fltk lib
from referencing cairo.
In both cases (--enable-cairo & --enable-cairoext), a new fltk_cairo lib is
created. This lib, similarly to local versions of png,jpeg and zlib,
is not generated if cairo is not enabled.
+ added cairo to fltk-config : now new --use-cairo flag is available
+ modified all unix like makefiles to now generate minimum cairo deps and also
new libfltk_cairo lib.
+ added new cairo subdir to permit conditional fltk_cairo lib generation.
+ vc2005 project minimum update to compile without be broken, but still needs
to create a similar fltk_cairo independent lib. For now, it works as before
with a dedicated cairo env. similar to --enable-cairoext context in unix.
+ regression tested ok with cairo disabled on win32, mac osx, mingw.
