 widths can be supported when line antialiasing is enabled. If an
            unsupported width is requested, the nearest supported width is used.
            Only width 1 is guaranteed to be supported; others depend on the
            implementation.  Likewise, there is a range for aliased line widths as well.
            To query the range of supported widths and the size
            difference between supported widths within the range, call <a class="citerefentry" href="glGet"><span class="citerefentry">
