0029312: Using OBB to speed up Boolean Operations

Browse Source 
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.

@subsection occt_algorithms_7_3a Options
The General Fuse algorithm has a set of options, which allow speeding-up the operation and improving the quality of the result:
* Parallel processing option allows running the algorithm in parallel mode;
* Fuzzy option allows setting the additional tolerance for the operation;
* Safe input shapes option allows preventing modification of the input shapes;
* Gluing option allows speeding-up the intersection of the arguments;
* Possibility to disable the check for the inverted solids among input shapes;
* Usage of Oriented Bounding Boxes in the operation;
* History support.
For more detailed information on these options please see the @ref occt_algorithms_11a "Advanced options" section.
