tdf#166035 thumbnailview: recognize some MS-format thumbnails
The sample I was given had thumbnail.emf.
Using Word 2010, I generated a powerpoint presentation
that had thumbnail.jpeg, and a spreadsheet that had thumbnail.wmf.
I imagine that other formats could easily exist.
But I don't know of a generic way to identify them,
since there doesn't seem to be any special
"this is where you find the thumbnail" pointer.
