Some remarks: I have seen in the past that the C++ style of comments (//) is not accepted by all C compilers (notably MSVC/C++ 9.0 or so, in C mode - there may be a flag to allow that). I will go and change these comments to regular C style, if you all agree. The line style and thickness are other aspects of an entry in a legend that we need to take care of. Of course, this makes the argument list a trifle lengthy, but there probably is no real alternative.
