image zooming function is not friendly

[mepleleo]

The image zooming function is not friendly. In the current version(1.4.0), the region to be marked cannot be found after the image is enlarged by pressing Ctrl. For example, Photoshop zooms the image by the current position of the mouse, which is convenient to operate. I hope it can be improved. Thks

I am using this software for annotating defects. Since we need a fine annotation, the image has to be zoomed in regularly. However constantly loosing the center point creates a big burden and greatly slows down the process. Please add this feature to the software.
The pull request mentioned above is stalled and there is no progress in that direction.
Thank you.

In case someone is interested: I have forked this repo and merged the changes from BestRevRome (#74) regarding this feature to the latest commit of the main repo (as of today: 4920f8e). It compiles under windows too (tested with visual studio 17 2022, QT 5.15).
