Nextcloud 13 expects FreeType support to be enabled in PHP GD #7454
Description
Since #6876 the system running Nextcloud should have FreeType support enabled in PHP GD; otherwise imagettfbbox and imagettftext would not be available (as explained in PHP Documentation) and the request to get the avatar would fail with an internal error.
This only affects auto-generated avatars, and does not prevent Nextcloud from running, so it should be notified to the admin in the settings page when the requirement is not met.
