Call this function before using any other GdkGLExt functions in your
applications. It will initialize everything needed to operate the
library and parses some standard command line options. argc and
argv are adjusted accordingly so your own code will never see those
standard arguments.
<note><para>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
gdk_gl_init_check() instead.</para></note>
