I'm not sure whether automatic linear scaling is really always the best
value for everbody ... there might be a perfomance impact for this on
old systems, too?

Maybe we should not care about such old systems anymore, but I think
that's rather something that we should revisit after the next release
has been done, and not do it now before the upcoming release.

Thinking about this for a while, I guess the automatic way is likely
better than adding more config options (we've got too many of those
already anyway)... but let's wait for the next release first. I think
after the release, we should do a major clean-up and also remove SDL1
support (SDL1 is decomissioned since more than 6 years now, so
everybody should now really use SDL2 these days).

Yes, that was the original intention. Not sure whether we still need
this now in 2020 since every recent machine should have GL support
now... maybe another thing to clean up after the next release...
