1 question.
As I see, I cann't to read and write image data in one session, i.e.
using one TIFF handle.
The problem in codec's setup. There are only one flags in libtiff
TIFF_CODERSETUP that indicate that codec inited for decode, or code process
(tif->tif_setupdecode,tif->tif_setupencode)

First call TIFFReadTile() for example codec setup for decode.
Then later TIFFWriteTile() but TIFF_CODERSETUP still set and
tif->tif_setupencode never called.
As a result libtiff crash in codec.

Is it known problem?
Is in plans to fix it?
Is problem with codec is only one problem to read and write image
with same TIFF handle?

Actually I can to fix it itself.
It is not dificult replace TIFF_CODERSETUP with 2 flags
TIFF_CODERSETUP, TIFF_DECODERSETUP and to control in initialization
code that only one flag could be set.

2. question
When next version of libtiff are expected?
If I make some useful changes in libtiff may I expect that this
changes will be included in libtiff? And how can I do it?
