- 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.
