Subject: [PATCH] xsettings: Round the Xft.dpi setting to an integer

When using gnome-tweaks to set a text scale factor that is not a
multiple of 0.25 (e.g. 1.1), Xft.dpi would be calculated as a
floating point number, which breaks the fdo spec:

Although GNOME could handle the floating point Xft.dpi, graphical
programs restrictively followed the above-mentioned spec would be
influenced negatively. For example, QT applications (running on
GNOME desktop) may ignore text scaling factor when Xft.dpi was
calculated as a floating point number:

The patch at the same time has few impact to GNOME itself.
