Caching and caching.. whole debate about that at bug 138068. Cairo one but
apparently broken (or I read it that way). And Skia might do another round with
an independent caching system. Another topic is. Is this related to DOCX filter
or not [have to check, don't remember]. As the filter tends to convert stuff..

So there is plenty of room/ 'potential' to have unintended memory issue with
images. That's the part worrying me. At obviously clear that even developers
struggle; else the would have seen bug 138068 from miles away (there is patch
in gerrit, no clue what that will do)
