1. Implementation of the user-defined option for usage of Oriented Bounding Boxes (OBB) in Boolean Operations for additional filtering (rejection) of selected for intersection pairs of sub-shapes. By default the usage of OBB is turned off. To enable/disable its usage the method SetUseOBB(flag) should be used. This method is available for all operations in Boolean Component. To enable/disable it in draw the command "buseobb 0/1" should be used. Note, that this will affect all subsequent operations. The OBB for the shapes are built by first necessity and stored into operation context (IntTools_Context). 2. Usage of the OBB in some test cases.
