  ScalarizeVecAndMatConstructorArgs on WGSL shaders.
  
  WGSL does not support mixing types in the constructors of vectors and
  matrices. Use the ScalarizeVecAndMatConstructorArgs traverser to
  scalarize these constructors and update it to cast to the destination
  type if the inputs are not in that type already.

  // Scalarize vector and matrix constructor args, so that vectors built from components don't have
