How to zoom/magnify on linux without compiz (bspwm)

I'd like to have the functionality described in [this video](https://youtu.be/sACNU_819TU?t=2m40s) . Basically, use super+scrollup/down or pinch in/out on my touchpad to zoom in a certain area of the screen like on a phone or tablet. Sadly I need compiz to get the described effect. How can I zoom in without using compiz? I'm using Arch Linux with bspwm + compton. What I've tried: * xzoom, which can zoom but spawns a new window instead of zooming in on the spot. Not what I want. * KDE's kmag, pretty much the same as xzoom but with a nice GUI. * Magnifier , where you can mouse over an area to zoom that area of the screen, which is not really what I want. I want to actually zoom in the whole screen like in the video above. There's are open issues in compton's repositories: * https://github.com/chjj/compton/issues/188 (dead repo) * https://github.com/yshui/compton/issues/43 (new fork)
