[metapost] MetaFun freelabel macro

[Oliver Buerschaper]

Dear Taco,

a minute ago I discovered this lovely macro freelabel() and friends …  
just a minor thing that confuses me a bit:

freelabel("a", origin, dir(90));

places the label below the origin rather than above it. I would have  
expected the direction vector to point from the anchor point towards  
the label and not the other way round …

Apart from that this nifty macro is going to save me a lot of trouble!
