Wrap poiu text rendering backend into this.
At the moment of writing:

    (gl:enable :scissor-test)
    (gl:blend-func-separate :src-alpha :one-minus-src-alpha :zero :one)
    (gl:scissor 0.0 0.0 (width-of poiu) (height-of poiu))
    (dolist (cmd (nreverse commands))
      (case (command-type cmd)
        (:scissor (apply-pretext-scissors cmd poiu))
        (:text (render-boxed-text cmd poiu))))
    (gl:blend-func :src-alpha :one-minus-src-alpha)
    (gl:disable :scissor-test)

Hackish, ad-hoc implementation, but probably would suffice for a trivial stuff.
