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>
