TransformProcessor nyní dědí ze třídy NOPProcessor, která nedělá nic, ale obsahuje všechen procesorový boilerplate a iteraci přes strom. Dá se z ní proto příjemně dědit. To dělá nový PandocProcessor, který by měl ořezat celý strom tak, aby v něm nebylo nic, z čeho by si mohl pandoc káknout do gatí. Ve formatitko.py je draft výstupu do markdownu pomocí pandocu, který ale actually docela sáčkuje, protože netriviální část chytrosti (jako třeba sbírání obrázků) se děje až v output generátorech. Relevantní k #40.katex-socket
