/// \deprecated HdSceneDelegate no longer implements GetTextureResource.

/// The functions below are used by the old texture system where the

/// Note: these functions are also not binding the Usd stage's
/// resolver context and thus don't handle some cases (e.g., model
/// search paths) correctly.
///
/// The corresponding functions for the new texture system are in
