guest window size is ignored

[Mike Wilson]

Using a guest window with smaller size than the guest desktop (using scrollbars to access the different areas of the guest desktop) is not honoured between restarts.

Setting a smaller window size on a 1600x1200 guest and shutting it down results in this data in the virtual machine xml file:

      <ExtraDataItem name="GUI/LastNormalWindowPosition" value="4,20,985,785"/>

The above looks fine, but when starting up the guest again, it expands to a larger size and updates the stored window position to this larger size (noticeable after shutting down again):

      <ExtraDataItem name="GUI/LastNormalWindowPosition" value="4,20,1592,1155"/>

Ticket #7042 is probably a related bug, where the guest window size is lost on every switch in and out of fullscreen.
