Flushing the Cairo context is necessary on Windows to make Cairo
drawings appear on the device (screen). This new method makes it easy
for user code to do this correctly after using Cairo drawings.
- add Fl::cairo_flush(cairo_t *)
- document Fl::cairo_flush(cairo_t *)
- reformat Cairo doxygen docs and code (partially)
- use the new method in Fl_Cairo_Window
- use the new method in test/cairo_test.cxx
- other minor (text) changes in test/cairo_test.cxx
- add test/cairo_test to the demo menu (test/demo.menu)
- remove separate libfltk_cairo to avoid cyclic dependencies, but
- keep a dummy libfltk_cairo in 1.4.0 for backwards compatibility
- move cairo/Fl_Cairo.cxx to src/Fl_Cairo.cxx
- add preliminary Cairo support for Visual Studio (MSVC)
Static linking is not affected by this change, but users building
with hand-made Makefiles will have to remove libfltk_cairo starting
with FLTK 1.4.0. The dummy library can be linked for backwards
compatibility but it will be removed later (in 1.4.x or 1.5.0).
The shared FLTK library libfltk.{so|dylib|dll|..} depends on libcairo
if and only if FLTK is built with one of the Cairo options. This has
always been the case for OPTION_CAIROEXT but is now also true if only
OPTION_CAIRO is selected, i.e. FLTK programs linked with a Cairo
enabled shared FLTK library will also be linked with libcairo. The same
is true for configure options --enable-cairo and --enable-cairoext,
respectively.
Preliminary Cairo support for MSVC now detects a Cairo installation
using the CMake variable FLTK_CAIRO_DIR which must be set by the user.
Note that this feature is temporary and may be changed in the future
for a better and more comfortable version.
... as discussed in fltk.coredev in thread "RFC: introduce public
config header <FL/fl_config.h>", see:
https://groups.google.com/g/fltkcoredev/c/xLCs1AIXMVo/m/MHZpQggzAQAJ
- Rename abi-version.h to fl_config.h, rename input files,
update dependencies, .gitignore, CMake, configure and Makefiles.
- Include Cairo options in FL/fl_config.h
- Rename FLTK_USE_CAIRO to FLTK_HAVE_CAIROEXT for consistency.
- Include <FL/fl_config.h> in config.h and wherever necessary,
fix include order (move FL/Fl.H to the top) and more.
- Move USE_X11 to fl_config.h and rename to FLTK_USE_X11
- Do not include <config.h> in Cairo demo program which is no
longer required in Cairo programs since FLTK 1.4.0
- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files
The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.
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.

Note: also fixed a typo in src/drivers/X11/Fl_X11_Screen_Driver.cxx

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.

+ 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.

This integration is minimum as discussed, in particular it does not feature any fltk cairo drawing substitution
as in fltk2.
Still it provides all the fundations to go further even in next 1.4 ...
By default *no* cairo features are implemented nor linked, it can only be activated by --enable-cairo
whose default is false.
Please visit the README.cairo for complete description.
+ fixed UTF8 compilation pb on linux ubuntu
+ minor comments fixes on the fly
