- specializes for 1, 2, 3 and 4-dimensional vector types which are then aliased as tvec1, tvec2, tvec3 and tvec4 - requires C++11 aliases; breaks compatability with C++03 - tested on: - clang-3.5.2, clang-3.8.0 - gcc 4.8.5, gcc 5.4.1, gcc 6.2.0 TODO: - still uses template template parameters - most can probably be removed - some definitions might now be de-duplicated
