Small correction to my earlier statement about GTK+ 3 versions:
- GTK+ 3 version *3.10* is required.
- GTK+ 3 version *3.14+* is highly recommended.
Such high version requirements are not due to the functions that do not
exist in earlier versions
(so far we only needed
gtk_widget_set_margin_start()/gtk_widget_set_margin_end() which are only
available since 3.12, but we work-arounded that
<https://github.com/darktable-org/darktable/commit/c572f6af886f80534253eb0598518b3ef79b3278>
),
but the state of custom theming in the GTK+ 3 - even in 3.14 there is still
some broken stuff in CSS...
