Pre-existing conditions *are* covered in POV-Ray, right?

Oops, sorry.  I myself have a pre-existing condition, and I live in the 
USA, where the people in charge don't know how insurance works, and 
believe that human life should be subordinate to market^H^H^H^H^H^H 
crony capitalist forces.

P.S.  As long as I've digressed into politics, please convey my 
appreciation to Chancellor Merkel for allowing herself to be on the 
losing side of the same-sex marriage issue.  Being the leader of the 
free world must be a difficult job.
