Added Fl::first_window(window) to change which window is at the top of
the window list. This window is used as the "parent" of any modal windows you create so it is a good idea to be able to change it. Normally it is whatever window got the last event. Fixed Fl_Menu::global handler to use first_window so if a modal window pops up in response it is parented to the window containing the menubar rather than the current top window. This was an annoying bug! Copied fl_line_style() and the line_style demo over from fltk 2.0 because I am tired of mailing this code to people. Better to advertise this as "added fl_line_style() function to set line thickness, dash patterns, and end caps". Fixed the documentation for these changes. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.0@1117 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
