I guess in this case its size is (10,log(10)) + pen size when drawn. > >> Multiplying such a path with (x,y) gives an object with size (1*x,1*y). >> In general: if the bounding box of an object has the size (a,b) and you >> scale it with (x,y), the resulting object has a size of (ax,by).

Now if you use pure numerics for scale, such as 'xscaled 2', this is interpreted as '2pt' (or 2*65536sp). If you use any dimension, it is also converted into scaled points. All the same for MP. If I'm right this should all be the same (untested) xscaled 2 xscaled 2pt xscaled (2*65536sp) 1 = 1pt = 65536sp >> I must admit that this wasn't clear to me before you came up with your >> question.
