Scan area isn't properly centered in the visible viewfinder

• @monsieurtanuki @g123k @M123-dev loosely related to [Scan] Half-image decoding is crashing on iOS #1581 which seems to be at a stalemate currently. I'm not currently clear as if of now, the focal point is defined by default at the middle of that vizor. It should be, because that's where users are going to put the barcode.

@teolemon I don't plan to approve #1582 as long as it uses copied/pasted code, when an elegant (and suggested) inheritance is possible.
I don't think the displayed viewfinder and the focus point are programmatically connected - though obviously the end-user would expect some consistency. I think we can even scan invisible barcodes, for instance a barcode hidden by the carousel.

This ticket is actually just a UI issue.
=> nothing related to the scan performance

I really love your draw @M123-dev, but I'm not sure where you want the visor to be.
Could you elaborate a bit more, please?

Sure @g123k the upper line is way shorter then the lower one. The ViewFinder should be centered in between the top and the carousel not directly below the "Clear" and "Compare" buttons

I used to have the scan area in the good position, but with recent updates, it's now on top of the screen.
