Hi, I'm having a lot of difficulty in controlling Arcs
and need help to understand what is expected in the arguments.
Even when I set inX=inY, and inRadiusX=inRadiusY, I get curves
that clearly are not arcs, but general bezier curves.

PdfPainter::ArcTo( double inX, double inY,
                   double inRadiusX, double inRadiusY,
                   double inRotation, bool inLarge, bool inSweep)

The doxygen header says inRadiusX/Y are the end point, but
clearly they are not when I examine the source.
It also looks like the previous MoveTo( x,y ) is important
in the geometry of the arc, from my experiments.

Can someone please explain this, and show a worked example of 
a simple 90 degree arc?

Thanks - Ian
