ba03dde15c Move probe_for_GTK() to class Fl_Posix_System_Driver from Fl_X11_System_Driver. 
Similarly move dlopen_or_dlsym().
This move is because GTK is not X11-specific.

4951fd1801 Better fix for issue #206. 
Albrecht caught a problem with my strncat use (see comments for 12d8da9c).

I noticed we have fl_strlcpy() and fl_strlcat() which is what was really
needed here.

62ff323b70 Add missing include file stdlib.h for abs(int)

macOS versions but maybe not in earlier macOS versions or with other
configuration options.

bd52db0b95 Added docs for public fl_vsnprintf() (STR #3413) 
Applied vsnprintf_v2.patch from STR#3413 which documents
the previously undocumented function, so that it shows up
here in the doxygen docs:

    Files -> File List -> vsnprintf.c -> fl_vsnprintf()

This commit does not solve STR #3413, just adds the recommended documentation
for fl_vsnprintf(). Other functions in src/vsnprintf.c could use docs too.

See the bottom of comment #5 in the STR for recommendations to fully solve.

a4866ffc21 Partial fix for issue #188. 
This fixes the inconsistency created by the possibility to change img->w() and img->h()
values. The fix is to use img->data_w() and img->data_h() that have constant values.

569fec25e0 Unification of scaled coordinate calculations in class Fl_Scalable_Graphics_Driver

bd6c985434 Improve Fl_Help_View test file 
- add DOCTYPE, <head> and <body> statements
- make the file more standards conformant
- update OL tests, add nested OL/UL test
- add 'alt' tags to image refs

Note: the 'NAME' tag is obsolete and should be replaced with 'ID'
but Fl_Help_View does not parse 'ID' tags (yet).

- rewrite to use pkg-config with both autoconf + CMake
- remove hardcoded library names
- fix build dependencies and search directories
- remove or replace old and unused variables
- update README files

To be done:
- implement fallback for autoconf/configure if pkg-config is missing

We don't have control over the code of these bundled libs, hence we

- C4996: The POSIX name for this item is deprecated.
         Instead, use the ISO C++ conformant name ...
