The UIS set doesn't distinguish - it's all just stars. I'm not sure
about other symbol sets. In reality, the difference is often arbitrary
and whether a particular area is best described as ice or snow or a
combination varies with time.
It looks like mpost/thArea.mp is the file for it, and I can see the
definition of p_ice_UIS in mpost/thPoint.mp, which presumably is a
single star. But how do I fill an area with that tesselated?
