License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
New search algorithm Extrema_ExtAlgo_Tree used in projection algorithm in Boolean Operations.
Extrema is set to search only min distance.
Add test case for this fix
Draw command projponf has been modified to provide possibility to change the default parameters of Extrema_ExtPS algorithm:
projponf f pnt [extrema flag: -min/-max/-minmax] [extrema algo: -g(grad)/-t(tree)]
-min - Extrema_ExtFlag_MIN;
-max - Extrema_ExtFlag_MAX;
-minmax - Extrema_ExtFlag_MINMAX (default);
-g - Extrema_ExtAlgo_Grad (default);
-t - Extrema_ExtAlgo_Tree;
Examples:
projponf f pnt -min - the parameters are Extrema_ExtFlag_MIN and Extrema_ExtAlgo_Grad;
projponf f pnt -t - the parameters are Extrema_ExtFlag_MINMAX and Extrema_ExtAlgo_Tree;
projponf f pnt -min -t - the parameters are Extrema_ExtFlag_MIN and Extrema_ExtAlgo_Tree;
