docs: Creates a perspective projection matrix with the given (x) FOV, aspect, near and far planes
  
  @param fov The field of view in the x direction
  @param aspect The aspect ratio, usually width/height
  @param near The near plane, cannot be 0
  @param far the far plane, far cannot equal near
  @return A perspective projection matrix built from the given values
