Using two different unit labels on the scale on the same linear gauge

[scstraus]

Hello and thank you for putting such a very useful set of widgets out into the world. I had a quick question which I fear the answer to is simply "no", but wanted to double check with you first.

I have a use case which requires a gauge which gives me values in two different units on the same gauge. The easiest way to explain it would be to imagine the example gauge code listed below (which I copied verbatim from the last example on your examples page), but instead of having it show the units only in Celsius, I would want it to have Celsius units listed on the top and Fahrenheit units listed on the bottom.

As there are already two scales with ticks and labels, one on top and one on the bottom of the gauge, it's more or less ready to do this, it just needs the ability to define those ticks and units differently for the two scales.

If it's not possible, please feel free just to say "nope, sorry, not possible" and close it, or if you are feeling ambitious, you are welcome to take it as a feature request :-).
