Migrate some DRAW tests which do not use external
CAD files and which do not use visualisation/image dump.
Some tests were modified, but the original idea was preserved
1. The partition operation allows splitting an arbitrary number of shapes of an arbitrary dimension
by other arbitrary shapes. The algorithm has been implemented in the class BOPAlgo_Splitter.
The API operator Splitter has been implemented in the class BRepAlgoAPI_Splitter.
2. The draw commands for usage the new algorithm have been implemented - bsplit and bapisplit.
The commands are identical, but one uses the BOPAlgo_Splitter, the other uses BRepAlgoAPI_Splitter.
Both commands should be used after Pave Filler is filled.
3. Test cases for the new algorithm.
4. Documentation has been updated.
Small corrections.
