Improve documentation for GtkCellRendererText:*-set properties
From https://bugzilla.gnome.org/show_bug.cgi?id=744052:
The GtkCellRenderer documentation has this explanation:
That’s great, though I guess it could give a bit of motivation about why the -set properties are needed. The problem is that it isn’t discoverable from the documentation of the individual properties in GtkCellRendererText, being in the introductory text for a different class.
How would you feel about a patch to slightly expand that explanation and reference it from the documentation for the -set properties?
Sure, that should be ok.
As for why we need it: We need to differentiate between unset (in which case we want to inherit style information from the parent/widget) and set (in which case we don't).
