Tilman Hausherr commented on PDFBOX-1931:
-----------------------------------------
PageDrawer.shfill() is called with a ctm that has a 0 scaling. That results
later that the radius of both circles is 0 :-( The pdf spec tells us: "If one
radius is 0, the corresponding circle is treated as a point; if both are 0,
nothing is painted." So the real work would be to find out why the ctm has a 0
scaling :-(
