QR code red area position scaled wrong when Pinephone is in landscape mode

Thank you for maintaining megapixels!

When pointing at a QR code, the red zbar preview area is positioned correctly when Pinephone is in portrait mode, but outplace when in landscape mode.

When tapping on the red area, QR code content is correctly shown, then the issue is just about position of the red area.

By moving the QR code, I noticed that this red preview area moves in the correct direction: it seems to me like just the scaling in the xy position of the red area vertices is wrong.

Just guessing, in main.c lines 315-321 width/height are switched based on device rotation situation, but in lines 422-429 this is not done for the zbar part. Sorry I would really like to test and suggest a verified solution, but I am not able to build a modified deb package...
