// RemoveDynamicIndexing is an AST traverser to remove dynamic indexing of non-SSBO vectors and

// matrices, replacing them with calls to functions that choose which component to return or write.

// We don't need to consider dynamic indexing in SSBO since it can be directly as part of the offset

// of RWByteAddressBuffer.
