When the logical layout mode is used, allow configuring the scaling to be non-integer. Supported scales are so far hard coded to include at most 1, 1.5 and 2, and scales that doesn't result in non-fractional logical monitor sizes are discarded. Wayland outputs are set to have scale ceil(actual_scale) meaning well behaving Wayland clients will provide buffers with buffer scale 2, thus being scaled down to the fractional scale. https://bugzilla.gnome.org/show_bug.cgi?id=765011
