Initialize gtkglextmm library.<p>
Call this function before using any other gtkglextmm functions in your applications. It will initialize everything needed to operate the library and parses some standard command line options. <em>argc</em> and <em>argv</em> are adjusted accordingly so your own code will never see those standard arguments.<p>
This function will terminate your program if it was unable to initialize the library for some reason. If you want your program to fall back to a textual interface you want to call <a class="el" href="namespaceGtk_1_1GL.html#a0">Gtk::GL::init_check()</a> instead.<p>
