// This is a GLSL implementation of
// "Computing the Singular Value Decomposition of 3 x 3 matrices with
// minimal branching and elementary floating point operations"
// by Aleka McAdams et.al.
// http://pages.cs.wisc.edu/~sifakis/papers/SVD_TR1690.pdf

// This should also work on the CPU using glm
// Then you probably should use glm::quat instead of vec4
// and mat3_cast to convert to mat3.
