Hi Umit,

I've actually just fixed the problem and checked it into svn/trunk.
It add an extra member variable though, so breaks the ABI, which makes
it undesirable to merge with OSG-2.8 branch.  Since that it's only the
wind contribution + mutliple precipitation effects that are effected
my guess is that it isn't such a serious issue as to merit breaking
the ABI in the OSG-2.8.x series.

As for rainy snow... or sleet as we call it in the UK, it should just
a case of adjusting the PreciptiationEffect parameters to get the
appropriate particle speed, size and colour.

The time when multiple precipitation effects might be more necessary
would be when transitioning between effects.

Robert.
