Last change on this file since 22fb7ab was 6d5e378, checked in by Martin Decky <martin@…>, 13 years ago

cherrypick GUI implementation (originally by Petr Koupy), with several major changes

  • for character-oriented devices a new output server and output protocol was created based on the original fb server
  • DDF visualizer drivers are pixel-oriented only
  • console and compositor can coexist in the same build
  • terminal widget is self-sufficient, no strange console nesting is needed
  • Property mode set to 100644
