			This routine prints out any OpenGL run-time errors pending and clears the errors. This routine typically should only be
			used for debugging purposes since calling it will slow OpenGL programs. It is provided as a convenience; all the
			routine does is call <a href="glGetError.3G.xml"><tt>glGetError</tt></a> until no more errors are reported. Any errors
			detected are reported with a GLUT warning and the corresponding text message generated by <a href="gluErrorString.3G.xml"><tt>gluErrorString</tt></a>.
		</p><p>
			Calling <tt>glutReportErrors</tt> repeatedly in your program can help isolate OpenGL errors to the
			offending OpenGL command. Remember that you can use the <i><tt>-gldebug</tt></i>option to detect OpenGL errors
			in any GLUT program.
