As I said before, nested decoders should be avoided whenever possible,
because properly forwarding everything between the caller and the nested
decoder is very tricky and almost never fully correct. For example, this
patch seems to break direct rendering.
And even if a nested decoder is unavoidable for some reason, it need a
lot more justification than none.
