When in 'small' window mode and attempting to open PAL ROMs larger than the

screen size (vertically), the window will open in partially truncated mode,
where the top of the PAL image is cut off.  This normally won't be a problem,
as it's mostly blank space anyway.

App window centering is now honoured when changing video zoom levels, not
just when changing eventhandler states.

Bumped version # for another test release.
