X_celent. Both scenes show pretty good what x-splines are capable of.

With all those new spline types I think it could be usefull to have an SDL 
option to determine the type of a declared spline. Although I don't see an 
immediate application for it now, it could be used to trigger switches in 
a macro.

#declare SPL = spline {
    	general_x_spline
    	<...> ...
}

#declare TYPE = splinetype(SPL);

where splinetype returns a value or a string that identifies the type of 
spline used.
