// For now it is used for the following two scenarios:
//   1. initializing gl_Position;
//   2. initializing ESSL 3.00 shaders' output variables (which might be structs).
// Specifically, it's not feasible to make it work for local variables because if their
// types are structs, we can't look into TSymbolTable to find the TType data.
