Both bugs can happen if a widget doesn't have an associated window()
or in similar situations. These fixes returns NULL to prevent crashes.
Bugs observed in special test scenarios, not real-life programs.
Function fl_read_image() obliges to keep a minimal use of global variable fl_window
also under the Wayland platform, even if its type (Window) makes little sense for
the hybrid library because it has its X11 value (given by X11/X.h) which is not
meaningful for the Wayland leg of the hybrid platform.
Virtual member function Fl_Surface_Device::as_image_surface() becomes useless.
... 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.
The X11 specific overloaded function fl_open_display(Display *)
has never been documented but exposed (and "exported" in the ABI)
in FL/platform.H which is not necessary. This internal function
is now static and no longer exposed in the ABI.
Don't confuse with fl_open_display() w/o arguments which is still
exported and declared in FL/platform.H.
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 first step replaces FL/x.H with FL/platform.H but keeps a small
FL/x.H that #include's FL/platform.H for backwards compatibility.
Documentation sources in documentation/src/*.dox have been fixed,
but references in other source files need to be fixed in another step.
Dependencies have been adjusted.
