[Thunar-dev] Something weird with thumbnailers (transparency and no drop shadow)

[Erlend Davidson]

I've written a thumbnailer for OpenDocument files (which doesn't need 
libgsf), but I notice thunar isn't putting the nice border shadow around 
the icons thumbnailed using this.  Furthermore, if I go into 
~/.thumbnails/normal and find the actual thumbnail image it has 
transparent parts!  The background colour (white) has been made 
transparent somehow.

My thumbnailer isn't doing it AFAIK, it simply does:
unzip -p "$ifile" Thumbnails/thumbnail.png | convert - -scale 
"$sizex$size" "png:$ofile"

and the original thumbnail.png files in the ODF are not transparent.  My 
guess is that the transparency is somehow killing the border.
