Image viewer
************

The image viewer is a simple dialog that displays the image contained
in one field of an Image column.  If launched from the data viewer,
the left arrow key shows the image in the same column from the
previous row in the current filter; similarly, the right arrow key
shows the image from the next row.  Double-clicking on the image shows
it in fullscreen mode; click on the fullscreen image again to close
the viewer.  When viewing a fullscreen image (including slideshows) on
Maemo Fremantle, the image will auto-rotate to match the current
orientation of the device.
