Call this function before using any other GTK+ functions in your GUI
applications. It will initialize everything needed to operate the
toolkit and parses some standard command line options.
argc and argv are adjusted accordingly so your own code will
never see those standard arguments.
Since 2.18, GTK+ calls signal (SIGPIPE, SIG_IGN)
during initialization, to ignore SIGPIPE signals, since these are
almost never wanted in graphical applications. If you do need to
handle SIGPIPE for some reason, reset the handler after gtk_init(),
but notice that other libraries (e.g. libdbus or gvfs) might do
similar things.
