Yeah looks like this is going to have to be done the hard way. The

guitarix code is definitely in cCbut it also use gtk_drawable which means

I have to convert it to cairo for gtk3.
So, I guess I will integrate the cairo code from fastmeter with the

"almost" c code from Tristans while using the guitarix port as a reference

 and trying to maintain the structure of hte original gtkmeter from JAMin

:-)
Oh yeah!
