 When using /W4 on Visual C++ or -Wpedantic on GCC, for example, the compilers will generate warnings for using C++ language extensions (/Za with Visual C++) such as anonymous struct.
 GLM relies on anonymous structs for swizzle operators and aligned vector types. To silent those warnings define `GLM_FORCE_SILENT_WARNINGS` before including GLM headers.

-By default GLM store quaternion components with the x, y, z, w order. `GLM_FORCE_QUAT_DATA_WXYZ` allows switching the quaternion data storage to the w, x, y, z order.
