[FFe] Move DPI settings over to use u-c-c settings.

[Brandon Schaefer]

[FFe] Connects the existing scale slider in the control center to existing code in the Unity shell so it will produce an effect.

Default settings are unchanged from current desktop defaults.

Do you plan on updating the gnome interface scaling-factor too?

In https://launchpadlibrarian.net/167214785/unity-settings-daemon_14.04.0+14.04.20140221-0ubuntu1_14.04.0+14.04.20140221.1-0ubuntu1.diff.gz we turned off the autodetection; it'd be good to do something with it via this slider. Might be tricky though as it's only an integer and not per-monitor.

Unity does not use the GTK scaling-factor setting. Even GTK-based applications become pretty much unusable if it is set to anything but 1, at least on my 13" 300 PPI test machine.

A slider to set the GTK text-scaling-factor would be useful for those GTK applications that can take advantage of it, but beyond the scope of the high-DPI shell work.

[Iain Lane (laney)]

hmm, well I don't have a way to test that.

In any event, it can be fixed separately. Ack to the FFe - please get it uploaded ASAP.
