The worldspace studiolight HDR images shipped in Blender have some
black/negative pixel artifacts, mostly in the brightest areas. These
are caused by the default downscaling filter that has negative lobes,
last time they were updated/added in e9df155d53. Fix the issue by
downloading already correct resolution (1024x512) from the source,
and recompressing with the same DWA quality setting.
