// Constructors and operators introduced in GLSL 1.20 - mostly on new
// (non-square) types of matrices.
//
// One important change in the language is that when a matrix is used
// as an argument to a matrix constructor, it must be the only argument
// for the constructor. The compiler takes care of it by itself and
// here we only care to re-introduce constructors for old (square)
// types of matrices.
