Here's a snippet of code to convert the inhg property value to mbar and then
use this to rotate the left-most digit on the mbar display.  The code
doesn't seem to work; Is this the correct usage of the <scale> tag?  I can't
find an example of its use for a 3D cockpit.  

<animation>
  <type>textranslate</type>
  <object-name>mb_digit_4</object-name>
  <property>/instrumentation/altimeter/setting-inhg</property>
  <scale>33.86</scale>
  <factor>.0001</factor>
  <step>1000</step>
  <!--<scroll>20</scroll>-->
  <axis>
   <x>0</x>
   <y>1</y>
   <z>0</z>
  </axis>
 </animation>

Thanks again,
Vance

Sounds indeed very reasonable and less complicated if the conversion is
the only thing he needs to be done.
