Thanks to jr hunting this down while I was busy with other things!

parser.cpp starting at line 5665
if ((Points[i][X] < 0.0) ||
     ^^^^^^^^^^^^^^^^^^^ and there we go.

            ((i > 1 ) && (i < Object->Number - 1) && (Points[i][Y] <=
Points[i-1][Y])))
        {
            Error("Incorrect point in surface of revolution.");
        }

The more I do this, the more I see exactly what clipka meant about the parser.

All of these tests and guards ought to be isolated in sor.cpp, not smeared all
over the source codebase.
