BMP format export file, I don't knwo what W means (World ?) Here is a
definition from Wikipedia, but I don't know if it is correct here :
"WBMP images are monochrome (black & white) so that the image size is kept to
a minimum. A black pixel is denoted by 0 and a white pixel is denoted by 1."

SWF is the Flash format extension.

GEOS is used for some spatial treatment. I think MS use it for EXPRESSION
parameter or some other else.

SHAPEFILE are managed directly by MS, I don't know for JPEG. So it is not
a "double-listing", as you could not have GDAL or OGR input but you always
got the INPUT=shapefile item.
