a dialog to customize the picking parameters.
Description of the dialog and associated parameters:
Height of the pyramid: define the length of each of the 6 pyramids of the cursor. The cursor is dynamically generated so that apexes of each pyramid touch the point sprite boundary, and height of pyramid is fixed.

Information window: allows defining the transparency (from 0% = opaque to 100% = transparent) and position of the windows. Possible values for position are:
Centred below the point
Top-left corner of the 3D view
Zoom at first selected point: This value is used to define the focal distance at the first selected point (at the end of the movement of the camera). This value is a ratio that will be multiplied by the current zoom value.
Picking optimisation: This section will be implemented only if the implementation of the picking function is based on vtkPointLocator functions. No parameters are needed if implementation is based on vtkPointPicker. (see Picking for more details).
Both parameters are used to customize the data structure of the searching underlying functionality.
