Made scalebox the way sway does it
Scaling a wlr_box without rounding can sometimes make the borders not connected and nice. I noticed this when setting scale in monrules to 1.2 So I've went and copied what Sway did in desktop/output.c but without having a second function and now using a random rounding macro I found on the internet so as to not use round from math.h.
