- templatize math library. All standard math classes (i.e. aiMatrix4x4) have been replaced by templates which are usually named like the old type with a 't' postfix. For compatibility, typedefs to replace the old types exist. For the C interface, these still map to raw structures.
While principally backwards-compatible, this is still a breaking change since I also changed some method signatures (i.e. aiVector3t<TReal>(TReal) is now explicit). Normal users should not be affected, though. git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@1129 67173fc5-114c-0410-ac8e-9d2fd5bffc1fpull/5/head
