PR is a quick fix for https://github.com/geoadmin/mf-chsdi3/issues/1680 (mixed type of PNGs)\r\n\r\nI don't see any configuration only solution, as Mapproxy knows only of type of PNG and does a lots of black magick to detect the `right type`:\r\n\r\nhttps://github.com/procrastinatio/mapproxy/pull/2\r\n\r\nCompare [Single
