Curves: Fillet and chamfer
Fixed a calculation error in the fillet operator. Limited the chamfer algorithm
to just run on the points inbetween the first and the last handles, since it
makes no sense to chamfer the start of a line. This brings a problem with
cyclic splines though, which will be addressed in a later commit.
