I've noticed that QuickDraw often fails when coordinates are
near or greater than 16000. What are the bounds within which
Quickdraw is guaranteed to work? In particular I'm trying to get
FrameArc to draw a circular arc of radius 702 about a center of
(14977,14965) at an angle of 91 and arclength 84. It fails to
complete the arc. Note that I am not talking about gaps in elipses
here, this is a circular arc.
You may wonder who needs to draw at such large coordinates.
There are reasons...
