Yes, good point.

Btw. I see now they require 128x128 pixels in the standard, but OpenOffice
still saves 181x256.  And I don't get why they want to force an alpha channel.
Probably because the Thumbnail Managing Standard does require it, which I
don't get neither.  Anyway, many of my ~/.thumbnails have no alpha channel.

I guess standards only go so far.

I tend to agree, so this point shouldn't go into the OpenRaster specification. 
In the meantime it could still be the fastest way to get thumbnails working.

Corrected.
