[Spice-devel] [PATCH spice-gtk 03/12] Add initial seamless mode support

Tue Aug 8 12:56:53 UTC 2017
From: Ondrej Holy <oholy at redhat.com>
Seamless mode is a way to use guest applications directly on the
client system desktop side-by-side with client applications.
Add toggle button to enable/disable seamless mode in spicy. If
seamless mode is enabled, client receive list of visible areas
periodicaly. Spice widget draw only visible areas (rest is
transparent). Spicy hide window decorations and show only
maximized spice widget. Spicy also set window shape to match
visible areas. Window shape is slightly bigger then visible areas
to avoid losing focus when resizing.
