When using logical sized monitors we are allowed to use fractional scaling but only if the resulting scaled logical monitor size is in integer form. So, in order to get this, we allow to scale the monitor to up to 8 fractional values per integer, doing some computation in order to fetch the nearest values which are closer to the scaling factors we can permit. https://bugzilla.gnome.org/show_bug.cgi?id=765011
