[virt-tools-list] [PATCH virt-viewer v2 0/3] Zoom related fixes

[Pavel Grunt]

Hi,
this small set of patches contains fixes for zoom related problems in virt-viewer.
The first patch fixes zoom operations in VNC guest when the window was resized [0].
The last patch enables resizing the window to any size [1] (allowed by the window manager)
by removing a part of the code which has been there since 2009. It also fixes problems
with wrong zoom used just after the connecting [2].

v2: just removed PATCH 3 of v1

I did a couple of tests to summarize changes:
1 - connect to a guest having greater desktop resolution than the client
2 - resize the window to be bigger than the client's screen
3 - zoom out, resize the window to resize the guest, set normal zoom
4 - keep zooming in to reach the maximal zoom then set normal zoom
