<p>A simple function node to remap numeric input values to another scale.</p>
<p>Currently only does a linear scaling.</p>
<p><b>Note:</b> This only operates on <b>numbers</b>. Anything else will try to be made into a number and rejected if that fails.</p>
<p><i>Scale and limit to target range</i> means that the result will never be outside the range specified within the result range.</p>
<p><i>Scale and wrap within the target range</i> means that the result will essentially be a "modulo-style" wrap-around within the result range.</p>
