Unbreak build of 2.13 with Qt4

[barracuda156]

@tibirna This builds with Qt4. Does it look sensible or can we improve something here?

[barracuda156]

@tibirna This is new in 2.13.

[tibirna]

Yes, I screwed it when fixing branch tag size, never caught it because of lack of Qt < 5.11 to compile/test with. Sorry. Thanks for catching it.

@tibirna When you get time, could you please take a look?

[tibirna]

Thanks a lot for the reprise. I looked over the code and left comments where requested. Things appear ok to me. Code compiles with Qt6 (apart from a new warning introduced by the latest, Qt 6.10, but it's not related to your changes) and the result seems to run properly.

Let me know when all is OK on your side and I will merge the pull request.

Thanks!

@tibirna Builds with Qt4 and apparently runs on x86, I will verify on powerpc now.

Upd. I think it works fine:

@tibirna Should be good to merge, provided you are satisfied with the current version of the patch.

@barracuda156 Thank you very much for your work, understanding and patience.
