ViewPortManager.setZoomInWidthLimit
Usage
void setZoomInWidthLimit(double width);
Description
Sets the viewport width at maximum zoom in.
In many applications, it is desirable to set a maximum zoom in level, instead of allowing the user to zoom in indefinitely.
This method determines the minimum allowed viewport width. It should be between 0 and 1. The default is 0.01, which means a maximum zoom in of 100x (the viewport see only 1% of the underlying surface).
