Improved altimeter instrument.
Adds enhancements allowing for calibration.

Jan, 2001 by Julian Foad <julianfoad@netscapeonline.co.uk>

Julian sez: 
 "provides a modified instrument definition with a knob
 driving a subscale showing through a cut-out in the face....
 
 I've put two lines in 'altimeter.xml', one to display millibars and
 another, presently commented out, for inHg; USA pilots might want to
 uncomment the inHg line instead.  At present, my subscale texture map
 only has marks on it, not numbers, so it can stay the same.  Really
 there should be two different versions of the altimeter, and a
 USA-registered C172 would be fitted with an altimeter with inHg while
 and a UK-registered C172 would be fitted with an altimeter with mb on
 its subscale."

This is an instrument configuration file for the open-source flight
simulator FlightGear (www.flightgear.org).  The file is an XML-encoded
FlightGear property list defining the instrument's layers and actions.

Each instrument is composed of layers stacked on top of each other.
A layer may be a texture (with transparent parts to show the layers
underneath), text, or a special layer that switches between two
others (say, to turn an indicator light on or off).  Each layer can
move independently in proportion to a property value, and text
can be generated from property values as well: all of the layer's
movements are defined as transformations.

Actions are hotspots on the instrument that will respond to a mouse
click.  Actions always modify the values of properties, either by
adjusting them, toggling them, or swaping them with other
properties' values.
