[MapProxy] transparent layers get an opaque background after merging

[Tobias Wendorff]

Hell... sometimes you just need to read the code AND documentation:
https://mapproxy.org/docs/nightly/configuration.html#image

This did it:

caches:
  cache_polygons_patterns_mixed:
    sources: [cache_polygons, cache_patterns]
    grids: [osm_grid]
    disable_storage: true
    image:
      transparent: true

Living in the code since v1.1.0 ;)
