Re: Caching intermediate compilation results for near-real-time PDF re-renders during editing

Hi Doug, thanks for your message. Yes I agree. This does not present
an issue, because the proposal is, when doing a "fast recompilation",
not to read in new values from the .aux file. So the table of
contents, equation references, etc, would not update. If the user
wants to update these, they can trigger a separate full compile. This
is how BaKoMa handles it, and it works very well.

Cheers,
Jamie
