/*
* Added check for "initiallyplaced" due to bug 13097:
*
* There are two possible cases in which a point can be inserted into a PlanarPolygon:
*
* 1. The figure is currently drawn -> the point will be appended at the end of the figure
* 2. A point is inserted at a userdefined position after the initial placement of the figure is finished
*
* In the second case we need to determine the proper insertion index. In the first case the index always has
* to be -1 so that the point is appended to the end.
*
* These changes are necessary because of a mac os x specific issue: If a users draws a PlanarPolygon then the
* next point to be added moves according to the mouse position. If then the user left clicks in order to add
* a point one would assume the last move position is identical to the left click position. This is actually the
* case for windows and linux but somehow NOT for mac. Because of the insertion logic of a new point in the
* PlanarFigure then for mac the wrong current selected point is determined.
*
* With this check here this problem can be avoided. However a redesign of the insertion logic should be considered
