Subject: Center overlay on primary screen
X-Git-Tag: v1.9.90~96
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=29b5d84eaac8eb317f31ee51e97e49adc621818a;p=tigervnc.git

Center overlay on primary screen

Makes sure it is readable in a multi screen configuration, as otherwise
it might end up crossing multiple screens.
