// The traverser: mostly pass through, except
//  - processing function-call nodes to push live functions onto the stack of functions to process
//  - processing selection nodes to trim semantically dead code
//
// This is in the glslang namespace directly so it can be a friend of TReflection.
// This can be derived from to implement reflection database traversers or
// binding mappers: anything that wants to traverse the live subset of the tree.
