<tt>glutStrokeWidthf</tt> returns the width in modeling units of a stroke character in a supported stroke
font. While the width of characters in a font may vary (though fixed width fonts do not vary), the maximum height
characteristics of a particular font are fixed.
</p><p>
<tt>glutStrokeLengthf</tt> returns the length in modeling units of a string (8-bit characters). This length
is equivalent to summing all the widths returned by <tt>glutStrokeWidthf</tt> for each character in the
string.
</p></div><div class="refsect1" lang="en"><a name="glutStrokeWidth.3GLUT-bugs"/><h2>Bugs</h2><p>
The deprecated <tt>glutStrokeWidth</tt> and <tt>glutStrokeLength</tt> routines return an
integer rather than a float. Newer GLUT programs should use the newer float-returning routine
<tt>glutStrokeWidthf</tt> and <tt>glutStrokeLengthf</tt>. Note that these newer float routines
do not exist in implementations prior to GLUT 3.8. Also, the <tt>glutStrokeLength</tt> routine summed
integerized character widths so it underestimated the length of strings prior to GLUT 3.8, but the implementation of
<tt>glutStrokeLength</tt> in GLUT 3.8 and beyond sums the character widths for the strings in a float
(though <tt>glutStrokeLength</tt> still returns an integer).
