[PATCH 0/3] ui/gtk: introducing vc->visible |

From: Dongwon Kim <dongwon.kim@intel.com>
Drawing guest display frames can't be completed while the VC is not in
visible state, which could result in timeout in both the host and the
guest especially when using blob scanout. Therefore it is needed to
update and track the visiblity status of the VC and unblock the pipeline
in case when VC becomes invisible (e.g. windows minimization, switching
among tabs) while processing a guest frame.
First patch (0001-ui-gtk-skip...) is introducing a flag 'visible' to
VirtualConsole struct then set it only if the VC and its window is
visible.
Second patch (0002-ui-gtk-set-...) sets the ui size to 0 when VC is
invisible when the tab is closed or deactivated. This notifies the guest
that the associated guest display is not active anymore.
Third patch (0003-ui-gtk-reset-visible...) adds a callback for GTK
window-state-event. The flag, 'visible' is updated based on the
minization status of the window.
Dongwon Kim (3):
ui/gtk: skip drawing guest scanout when associated VC is invisible
ui/gtk: set the ui size to 0 when invisible
ui/gtk: reset visible flag when window is minimized
