BUG: Gaps Between Wedges Drawn with Pie()

MORE INFORMATION

Pie() takes the following parameters:

   BOOL Pie( HDC hdc,
             int nLeftRect,
             int nTopRect,
             int nRightRect,
             int nBottomRect,
             int nxStartArc,
             int nyStartArc,
             int nxEndArc,
             int nyEndArc )
				

Pie() draws a pie-shaped wedge by drawing an elliptical arc whose center and two endpoints are joined by lines.

Using Pie(), if two pie wedges are drawn with the same bounding rectangle and the end point of the first wedge is equal to the start point of the second wedge, there can be a gap between adjacent wedges. This gap shows up only with certain pie sizes and certain start/end points.
