I've written and tested locally some mimetypes for raw images and for 
xmgrace (.agr) files.  I can install these manually, although I haven't 
got automake to install them properly yet.

As for speeding up raw thumbnails, I think just now I'll go with having 
a small program like "thunar-vfs-pixbuf-thumbnailer" (or 
"thunar-vfs/thunar-vfs-thumb-jpeg.c" if the dcraw images have the exif 
data in them) with thunar-thumbnailers that takes a jpeg (or other 
format) from stdin and produces a scaled-down png.  This is pretty 
quick, the whole process takes about 0.1s on my machine (c.f. 1.5s when 
using convert).  A longer term solution might be to write something 
similar to dcraw just for thumbnails that uses libopenraw, once that 
supports all the formats.

Once I get mimetypes to install properly I'll commit an (xm)grace 
thumbnailer to the svn.  I've put a limit of 30MB so .agr files bigger 
than this won't be thumbnailed.  This is a bit a a random size to choose 
though, as the real value should probably depend on the amount of 
(free?) memory available on the system, so I'll change that if others agree?

Has the font thumbnailer been dropped now?  Do you want this in 
thunar-thumbnailers?
