The new reshape callback function.
</dd></dl></div></div><div class="refsect1" lang="en"><a name="glutReshapeFunc.3GLUT-description"/><h2>Description</h2><p>
<tt>glutReshapeFunc</tt> sets the reshape callback for the current window. The reshape callback is
triggered when a window is reshaped. A reshape callback is also triggered immediately before a window's first display
callback after a window is created or whenever an overlay for the window is established. The
<i><tt>width</tt></i> and <i><tt>height</tt></i> parameters of the callback specify the new window size
in pixels. Before the callback, the current window is set to the window that has been reshaped.
</p><p>
If a reshape callback is not registered for a window or <tt>NULL</tt> is passed to
<tt>glutReshapeFunc</tt> (to deregister a previously registered callback), the default reshape callback is
used. This default callback will simply call <tt>glViewport(0,0,width,height)</tt> on
the normal plane (and on the overlay if one exists).
</p><p>
If an overlay is established for the window, a single reshape callback is generated. It is the callback's
responsibility to update both the normal plane and overlay for the window (changing the layer in use as necessary).
</p><p>
When a top-level window is reshaped, subwindows are not reshaped. It is up to the GLUT program to manage the size and
positions of subwindows within a top-level window. Still, reshape callbacks will be triggered for subwindows when their
size is changed using <a href="glutReshapeWindow.3GLUT.xml"><tt>glutReshapeWindow</tt></a>.
