cairo_user_font_backend_t changes of poppler/CairoFontEngine.cc were committed in rev 1.21. And the changes were commited with the following log message: * glib/poppler-action.cc: * glib/poppler-document.cc: * glib/poppler-page.cc: * poppler/CairoFontEngine.cc: * poppler/CairoFontEngine.h: * poppler/CairoOutputDev.cc: * poppler/CairoOutputDev.h: * poppler/Gfx.cc: * poppler/TextOutputDev.cc: Fix various memory leaks. But there isn't cairo_user_font_backend_t in the official cairo repository yet. It's a wrong commit, wasn't it?
Yup, that was an accidental commit. I've backed the changes in question out again.
