GLM 0.9.3.0 is finally released. Since the branch 0.9.2, the test bench and the Doxygen API documentation has been expend.

Swizzle operators are a challenging task to implement but thanks to the effort of many contributors, GLM 0.9.3.0 provides finally something interesting even if
|
|
|
not perfect but still a great improvement considering the incompatibilities with some external libraries. GLM 0.9.3 provides two implemetanations, one for C++ 98
|
|
|
compilers and one for C++ 11 compilers providing an implemetnation closer to what GLSL does. Indeed the C++ 98 implementation is compatible with C++ 11 compilers.
