These circles are really intriguing...

I did not have "xyscaled(.a.,.b.)" but instead I had 
"xyscaled (OverlayWidth,OverlayHeight)" and when I 
replace that with "xscaled (.a.)" I get this:

"! transform components aren't all known" 

My present definition is 

\startreusableMPgraphic{omcirkeld}
   draw fullcircle xscaled(.a.)
     withpen pencircle scaled OverlayLineWidth
     withcolor OverlayLineColor ;
\stopreusableMPgraphic
