1) Improve and clarify documentation:
- update, reformat, and reorder parts of CREDITS.txt
- make sure that documentation appears in doxygen docs
- add '\since 1.4.0' to documentation of new methods and functions
- remove doxygen's '\brief' where not required (we're using
JAVADOC_AUTOBRIEF = YES)
- clarify screen scaling, scaling factor, and related stuff
- add more info about backwards compatibility for X11 specific code
2) Update dependencies
Note: one goal is to have to edit fewer version numbers in source
files for each release.
We may be able to generate some files by the build procedure (CMake)
to avoid editing them in the future (1.5.0 or later).
- 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.
Files without '.txt' suffix can't be handled well by Windows (users),
hence renaming such text files to *.txt makes FLTK more "Windows-friendly".
There are a few exceptions (this is intentional): README and other files
in bundled libraries (maintained upstream) are not changed.
