Compiler warning: comma at end of enumerator list [-Wpedantic]
Note 1: I decided to fix these warnings although trailing commas in
enums are allowed at least since C++11.
Note 2: I fixed only public headers because these headers may be
compiled in user code. To do: check internal headers.
- 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.
