With this, fl_copy_offscreen() can be used with any drawing surface (e.g., PostScript) and any Fl_Offscreen
argument (e.g., returned by Fl_image_Surface::offscreen()).

Main point: pthreads must not be checked under Windows (e.g. MinGW)
since Windows always uses native Windows threads (unless Cygwin is used).

the same as the check which is subsequently used before calling dlsym() and dlopen().
Note that this may also work around an occasional issue observed when building
for Windows with cmake and mingw-64, which was sometimes erroneously attempting
to #include "dlfcn.h" - which is not generally appropriate on a Windows host.

mGapEnd should reflect the total allocated size after the constructor
is executed, i.e. the text buffer is empty. This was not the case.
See thread "Fl_Text_Buffer constructor bug" (2016-12-05) in fltk.general.
The bug was harmless, but the pre-allocation did not work as expected, i.e.
the pre-allocated buffer size was allocated but effectively ignored later.

Make config.h generated by configure and CMake better comparable.
Note: these options were defined in configh.cmake.in and implemented
only in CMake. Implementation in configure is still missing though.

This ensures API compatibility with FLTK 1.3 where Fl_Surface_Device->set_current()
is used to change the current drawing surface.

Fl_RGB_Image's of depth-2, that is, monocolor and transparent, were not drawn using the XRender extension,
when present, as are depth-4 images. With this change they are.
A by-product of this change is that it fixes an erroneous drawing (STR#3353) that occurred when
the image expands outside the window.

FLTK_ABI_VERSION has been renamed to FL_ABI_VERSION in FLTK 1.4.0.

The problem is specific to the X11 platform. The cause is that depth-2 images were not considered
in a previous change (r.10628) that introduced transparent image drawing with alpha blending.
Depth-2 images can be processed just as depth-4 images with alpha-blending.

Missing FL_EXPORT statements (attributes) affected only the configure/make
build because some compiler and linker options (visibility etc) are not
yet implemented in the CMake build.

It is reserved as the recommended build directory for CMake.

This is branch-1.4, and that commit was not intended to be in branch-1.4.
branch-1.4 is the current active development branch for FLTK 1.4.
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12103 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
The new development branch is now branch-1.4.
See important notes below.
------------------------------------------------------------------------
Note to svn (subversion) users: This branch (branch-1.3-porting)
is finished since the release of FLTK 1.3.4.
The new development branch is now branch-1.4 -- please checkout a new,
clean svn working copy if you want to get branch-1.4 (previously
branch-1.3-porting).
------------------------------------------------------------------------
Note to Git users: if you used the Git branch 'branch-1.3-porting'
to get the FLTK 1.4 development branch, then you need to switch to
branch-1.4 now, which is the official current development branch.
Please checkout branch-1.4 (after git fetch or git pull), and you're
done.

Added FLTK 1.3 CHANGES file as CHANGES_1.3, updated CHANGES to start
release info (changelog) for FLTK 1.4.
You can update the svn configuration of your working to get this
branch if you previously used branch-1.3-porting:
$ svn switch http://seriss.com/public/fltk/fltk/branches/branch-1.4
If you used branch-1.3 previously we recommend to checkout the new
branch-1.4 in a new working copy.
