Allow circle arrowheads when mag >= 42, ticket #52
|
||||
|
||||
Circle and half-circle arrowheads would be drawn with 40 + mag/4 points by
|
||||
calc_arrow() in bound.c. However, the point arrays passed to calc_arrow()
|
||||
would only contain 50 points. With a magnification >= 42, a buffer overrun
|
||||
would occur. Simply use 40 points, independent of magnification.
