Is there any reason why sp-ellipse.cpp uses .552 as the ellipse-to-bezier constant rather than something with a few more digits:<br><br>&nbsp;&nbsp; 0.55228474983079356<br><br>I know it probably makes little visual difference, but why not use the exact number if you have it?&nbsp; I certainly wouldn&#39;t use 
3.14 for PI.&nbsp; So why use .552 when you mean 4*(sqrt(2)-1)/3?<br><br>--bb<br>
