desktop.el is intended for restoring the state of a buffer.  Use
desktop-save and desktop-read for restoring your projects.  After
using desktop-save, you can kill a buffer without previews getting

If you think that you want an interface that will selectively work on
single files, it makes much more sense to make this a feature request
for desktop.el rather than ask for preview-latex implementing trickery
to bypass desktop.el.

Probably desktop.el should get a possibility of marking a buffer as
load-on-demand, restoring it when it actually gets loaded, the way
saveplace.el works.
