I see that might be a problem due to the formula support for some points. If 
also relative values have to be taken into consideration it makes the 
calculation of the path harder. Now the points can just be calculated when a 
parameter changes without the need to take the previous point into account. 
This is no problem for normal pathes as they are not modified via parameters.

I don't see that we win anything if we also allow relative values.

Have a nice week,

Thorsten
