glutCreateWindow creates a top-level window. The name will be provided to the window system as the window's name. The
intent is that the window system will label the window with the name.
</p><p>
Implicitly, the current window is set to the newly created window.
</p><p>
Each created window has a unique associated OpenGL context. State changes to a window's associated OpenGL context can
be done immediately after the window is created.
</p><p>
The display state of a window is initially for the window to be shown. But the window's display state is not actually
acted upon until <a href="glutMainLoop.3GLUT.xml"><tt>glutMainLoop</tt></a> is entered. This means until <a href="glutMainLoop.3GLUT.xml"><tt>glutMainLoop</tt></a> is called, rendering to a created window is ineffective because the window
can not yet be displayed.
</p><p>
The value returned is a unique small integer identifier for the window. The range of allocated identifiers starts at
one. This window identifier can be used when calling <a href="glutSetWindow.3GLUT.xml"><tt>glutSetWindow</tt></a>.
</p></div><div class="refsect1" lang="en"><a name="glutCreateWindow.3GLUT-x_implementation_notes"/><h2>X Implementation Notes</h2><p>
The proper X Inter-Client Communication Conventions Manual (ICCCM) top-level properties are established. The
<tt>WM_COMMAND</tt> property that lists the command line used to invoke the GLUT program is only
established for the first window created.
