Use something like this not tested macro. It approximates circle with linear
spline. Use Accuracy between 0 and 1
#macro QuarterOfCircleSpline(Center,Radius,Accuracy,Angle)
#local S=spline{
#local Counter=0;
#while (Counter<Angle)
Counter (vrotate(x*Radius,y*Counter)+Center)
#local Counter=Counter+Angle*Accuracy;
#end
Angle (vrotate(x*Radius,y*Angle)+Center)
};
spline{S}
#end
Adjust further to your needs.
