The temperature map average equity is calculated as:

loop over dice rolls
   find best move on n-ply
   calculate equity of resulting position at n-ply


A "regular" n+1 ply equity is calculated as

loop over dice rolls
   find best move on 0-ply
   calculate equity of resulting position at n-ply


This may, apperently, give small differences in equities.

There is... but it's written for GTK+ 2.x. Unfortunately the windows
version is build with GTK+ 1.3, so this function is not available (yet).
