Extra question: how about extending the current behavior found in
https://github.com/kovidgoyal/calibr...r/from_html.py so instead of enforcing a white background (as per line 353), it would first check whether a value has been supplied in the CSS? Something like paged_display.set_background() to be implemented within paged.coffee (at least being able to change the color would be nice; of course it would be even nicer being able to set backgroundImage and backgroundCover properties).
