Refactor JoinVerticesProcess to utilize the new utility. ADD basic operators for aiColor4D, move to dedicated header and implementation file. ADD some utility functions to SpatialSort. ADD my existing Catmull-Clark implementation to Assimp for all model formats with support for subdivision surfaces. Slightly WIP, likely to produce errors on non-closed meshes. Currently only implemented in the AC3D loader. Switch to byteswap intrinsics instead of inline assembly (bswap). Currently MSVC only. FIX phong shading in assimp_view. VertexTriangleAdjacency class now also works on arbitrary polygons - UNTESTED, tbd. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@532 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
