New Features and Extensions

- fltk-config allows to compile multiple files with more compiler and linker
    options given on the commandline.
  - fl_contrast() functionality has been improved, adding a new contrast
    calculation method based on human contrast perception. This new function
    is now the default but the old, less accurate, contrast function can be
    chosen as an option.
  - Timeout handling has been unified across platforms (#379), see documentation
    in chapter "Migrating Code from FLTK 1.3 to 1.4".
  - New Fl::remove_next_timeout(...) to remove only one timeout (#992).
  - New fltk-options executable, improved Fl::option documentation.
  - New function `Fl_Window::get_size_range()` (#981).
  - New FL_DEPRECATED macro to flag deprecated functions and methods.
  - Enable suppression of "deprecated" warnings by macro FL_NO_DEPRECATE.
  - New animated GIF images support (Fl_Anim_GIF_Image class) (#375).
  - GIF and BMP files can now be "read" from memory, i.e. they can be included
    in source code (use their new constructors).
  - New Fl_Scheme_Choice widget can be used to easily switch schemes in apps.
  - A new scheme named "oxy" has been added (STR 2675, STR 3477).
  - Drawing "Arrows" has been unified in all core widgets.
  - Drawing "Radio Buttons" has been unified in all core widgets.
