commit f2d96b4df221d922ededfbff9236636273a56029
Author: Jehan <jehan girinstud io>
Date: Mon Nov 30 00:05:00 2020 +0100
gexiv2: more variants with GError instead of WARNINGs.
This gets rid of all functions which could fail with a LOG_ERROR(),
which was basically raising a GLib warning. Use GError instead as this
is much easier to process for using applications.
For API stability, it results in new public functions, while the
existing ones keep behaving the same yet are now deprecated in favor of
the new ones.
