is there any mechansim built into LibTiff to prevent it from reading all 
tags into memory when you do a TIFFSetDirectory ?

some applications store gigantic quantities of image meta-data in certain 
tags, and LibTiff happily allocates gigantic quantities of RAM to store 
this tag data, when all I really want is to query the image dimension or 
DPI tags.

i see the TIFFReassignTagToIgnore function, but i'm not sure it actually 
does anything... the arrays it fills aren't used anywhere.
