    Writer image export: cmd. line, default to white background
    
    This commit fixes the writer image export (jpeg, png) that didn't
    work because the export pixel size was set to 0 by default. Now
    the default is set to document size (which depends on system DPI).
    
    When exporting to a PNG the background was transparent, which may
    not  be desired. The background color is now by default white and
    can be changed for DocumentToGraphicRenderer, but the dialog or
    command line don't support such an option - for now.
