SurfaceMesh from glm types

[Jeordanis]

Hi! I started playing with your library today. It is very different from what I'm used to but I like it so far. Thanks!

I was wondering if we have a way to use glm types instead of Eigen to create and manipulate meshes/geometry.

For me, this is more intuitive:

  std::vector<glm::vec3> points;
  points.emplace_back(glm::vec3(0,0,0));
  points.emplace_back(glm::vec3(2,0,0));
  points.emplace_back(glm::vec3(2,0,2));
  points.emplace_back(glm::vec3(0,0,2));

Than this:

  const size_t vCount = 4; 
  Eigen::MatrixXd vertexPos(vCount, 3);
  vertexPos << 0, 0, 0,
  2, 0, 0,
  2, 0, 2,
  0, 0, 2;

I find Eigen too complex for my needs. Is the whole library using Eigen by default?
