Double precision & adaptable z dimension

[Charles Seman]

Jim,

Please find a new version of the skewt.gs script I sent you:  this
version uses "kelvin" = 273.15 instead of "tfreeze" = 273.16 for
temperature conversions from Kelvin to Celsius.  I am sorry for this
error, and hope it has not caused any problems for you.

Sincerely,
Chuck
