tigervnc/u_tigervnc-use_preferred_mode.patch

Author: Michal Srb <msrb@suse.com>
Subject: Use preferred mode.
Patch-Mainline: To be upstreamed
References: bnc#896540

If there is any resolution specified with -geometry or -screen parameters,
report this resolution as preferred one. That way desktop environments won't
change it immediately after start.
