MiterJoin doesn't work

[Google Code Exporter]

It appears that MiterJoin doesn't do anything at all. From reading the source 
code, if the Join style is not RoundJoin or BevelJoin, then the Joiner returned 
is the RoundJoiner. Although in my case, RoundJoin doesn't seem to work either 
(I always get a bevel).

Actually cap styles don't seem to do anything either.
