Last change on this file since 1254 was 1254, checked in by Sam Hocevar, 16 years ago
  • Use the LSB of alpha and blue components to encode additional flags such as bold or underline. No higher level support for these yet, but at least everything is consistent.
  • Created cucul_set_attr_ansi() and cucul_set_attr_argb() which are bound to replace cucul_set_color() and cucul_set_truecolor().
  • Property svn:keywords set to Id
