Pierre fixed it nicely. Was a mistake I did.
The class TRSVGPath makes direct call to Athens. So Athens does all the job.
Cheers,

Hi Peter!
This is a problem we have had for a while. I did not think about comparing it with the
path.
We will rewrite RTBezierLine to use TRSVGPath
How the bezier is computed for
TRSVGPath?
We will let you know
Cheers,
Alexandre

Hi,
it seems that last control point of a bezier line is off.
Here is a comparative view of RTBezierLine (black line) and bezier line done with SVG
(red line). Notice how the bottom half is flatlined and doesn't match up.
<2015-04-28_00:29:16.png>
And the code (based on RTRoassalExample>>exampleBezierCurve):
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| v e1 e2 l s p1 p2 path svg|
v := RTView new.
e1 := (RTEllipse new size: 15; color: (Color blue alpha: 0.4)) element.
e2 := (RTEllipse new size: 15; color: (Color blue alpha: 0.4)) element.
e2 translateBy: -150 @ 150.
p1 := RTBox element.
p2 := RTBox element.
p1 translateTo: (e2 position x + e1 position x / 2) @ e1 position y.
p2 translateTo: (e2 position x + e1 position x / 2) @ e2 position y.
v add: p1.
v add: p2.
s := RTBezierLine new.
s color: Color black.
s controllingElements: (Array with: p1 with: p2).
l := s edgeFrom: e1 to: e2.
v add: e1.
v add: e2.
v add: l.
path := 'M -150 150 Q -75 150 -75 75 Q -75 0 0 0'.
svg := RTSVGPath new borderColor: Color red; path: path; element.
v add: svg.
