commit f748969aa063a188e7215ec6b7ff8c1c41ce25c1
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date:   Fri Nov 10 09:05:51 2017 +0100

    Replace broken SVGs with higher-resolution PNGs.
    
    In fact, we're generating all PNGs on higher resolution now and
    scaling them down on the graph pages. If this turns out to be a
    performance issue, we'll have to provide two versions, but let's try
    it out first.
    
    Fixes #23965.
