Unlike pango_font_description_from_string(),
pango_font_description_set_family() requires a already properly
formatted font family string. The proper format is a comma seperated
list of font families, but we generated a "comma space" separated list.
Passing a incorrectly formatted font family string to pango seems to
cause wierd issues, where the wrong font is sometimes selected.
For example, this fixes a font selection issue on zh_TW.UTF-8 locale for
chinese characters, where previously the "Droid Sans" font was selected
instead of "Source Han Sans TW" even though fontconfig had placed
"Source Han Sans TW" before "Droid Sans".

If a source actor is set, use that for determining the arrow side (i.e.
whether the BoxPointer widget should expand in a certain direction).
This is better because it ensures that the popup is displayed on the
same monitor as the widget it originates from.
Without this, entering text with a vertically aligned input method
close to the bottom of a monitor would expand the BoxPointer downwards
on the monitor beneath it, instead of upwards, which is what one would
expect.

Now that full-sized window previews are allowed again it makes sense to
align the window previews with the pixel grid to prevent unscaled
windows from looking blurry in the overview.
Every action has specific associated terms that
identify that action and show it in the search
results. Methods to match the actions as well
as getting properties of specific actions are
needed in order to provide a way of using the
actions.
