This method updates a value at the specified offset in the vector (in linear
time). The vector will automatically be resized if it is not large enough.

<p class="para">
Since the <a href="class.pht-vector.html" class="classname">pht\Vector</a> class supports array access,
updating values can also be performed using the array subset notation
(<em>[]</em>).
