Comment 7 for bug 611907

rs274x - as crappy as it is - states "Multiquadrant interpolation *can* produce arcs that are larger than 90° and also
circles." (my emphasis). nowhere (in revision f) is stated, that g75 can't be used for arcs <=90°. it may imply, that it should though. anyway, it's your choice, i'm out of this discussion.
