annotate tern.h @ 1483:001120e91fed nuklear_ui

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Skip loading menu ROM if Nuklear UI is enabled. Allow disabling Nuklear UI in favor of old menu ROM both at compile time and in config. Fall back to ROM UI if GL is unavailable
