If there are small backports you would like be included in an updated build of DSPlayer 17.6 64bit, feel free to propose them.

For now i included:
- Better global GUI scaling (You can now use 1080px or even 2160px-height artwork without scaling distortion issues. The new scaling is applied to all GUI graphics, so also scaling of icons etc. looks better now.)
- Addon Manager: Show "Update all" entry if there is 1 or more updates available (had to be 2 before)
- Parent folder focus save fix (https://github.com/xbmc/xbmc/pull/15680)

I have absolutely no idea if what I'm going to ask is doable as a simple backport but I feel it needs to be asked. Is updated InputStream plugin support possible? Mainly thinking about the new, legal, Netflix/Prime Video plugins here. If those could be made to work with Kodi DSPlayer... well, it would be quite an achievement.
Again: it might be extremely hard/impossible to do. Just asking and asking because InputStream was introduced with Kodi 17, so work should not be totally from scratch (hopefully).

Edit: I read in the Kodi 19 HDR Edition discussion that plugins are starting to migrate to Python 3. When that becomes widespread... that's going to be quite a big step towards the end of Kodi DSPlayer. No updated plugins means no updated scrapers. At that point... there's little left if one cannot update his/her library.
