BUG

Eigen

• c++17 can not use operator new to create class with Vector4f or Matrix4f (but work for vector3f and Matrix3f), back to c++11 with macro EIGEN_MAKE_ALIGNED_OPERATOR_NEW fix it. (MinGW-64 8.1.0 win10)
• callback function cannot do assignment to Matrix4f, alignment problem Cause 4, with compile flag -mstackrealign;

c++

• template derive
  • through a non-template base class

quaternion

• elegent transformation to rotation matrix
