Thumbnail size causing moving targets

[Steven Garrity <stevelist silverorange com>]

I'm sure this has been dealt with before, but the mailing list search on 
 gnome.org is broken, and I couldn't find anything browsing the 
archives manually.
Because the size of thumbnails is different than the size of the 
temporary icon while thumbnails are generated, icons an jump around 
while thumbnails are being generated.
For example, if you take a large directory with hundreds of photos, and 
scroll down to the bottom before all of the thumbnails have loaded, you 
will see the icons jump around as the thumbnails load and the contents 
of the folder are re-layed-out accordingly.
Has there been any consideration for a fixed thumbnail area that is the 
same size as the "generating thumbnail" icon, as in Windows XP, so the 
folder contents don't move as thumbnails are generated?
Again, sorry if this has already been dealt with - feel free to just 
point me at an old rationale for the current behavior.
Thanks,
Steven Garrity
