docs: Set this matrix to be a symmetric perspective projection frustum transformation for a left-handed coordinate system
  using OpenGL's NDC z range of <code>[-1..+1]</code>.
  <p>
  In order to apply the perspective projection transformation to an existing transformation,
  use {@link #perspectiveLH(float, float, float, float) perspectiveLH()}.

  @param fovy
  the vertical field of view in radians (must be greater than zero and less than {@link Math#PI PI})
  @param aspect
  the aspect ratio (i.e. width / height; must be greater than zero)
  @param zNear
  near clipping plane distance. If the special value {@link Float#POSITIVE_INFINITY} is used, the near clipping plane will be at positive infinity.
  In that case, <code>zFar</code> may not also be {@link Float#POSITIVE_INFINITY}.
  @param zFar
  far clipping plane distance. If the special value {@link Float#POSITIVE_INFINITY} is used, the far clipping plane will be at positive infinity.
  In that case, <code>zNear</code> may not also be {@link Float#POSITIVE_INFINITY}.
