* plug-ins/jpeg/jpeg-settings.c (jpeg_swap_original_settings): new
function that swaps the vertical and horizontal axis for the saved
subsampling parameters and quantization tables.
* plug-ins/jpeg/jpeg-exif.c (jpeg_exif_rotate): swap the saved
settings when the image is rotated. Fixes bug #466593.
* devel-docs/release-howto.txt: added note about having admin
access to Bugzilla and to the news section on www.gimp.org.

* plug-ins/jpeg/jpeg.[ch]
* plug-ins/jpeg/jpeg-save.[ch]: in the JPEG save dialog, removed
the option "Force baseline JPEG" and added the new option "Use
custom quantization tables" to allow resaving a JPEG file with the
same compression settings as the original file. This is useful if
the quantization tables are different from those that can be
created by the IJG JPEG library.
* plug-ins/jpeg/jpeg-settings.[ch]: updated comments, changed the
return type of jpeg_restore_original_tables() because the IJG JPEG
library expects unsigned integers.

* plug-ins/jpeg/Makefile.am
* plug-ins/jpeg/jpeg-quality.[ch]
* plug-ins/jpeg/jpeg-settings.[ch]: new files including functions
for detecting the quality setting of existing JPEG files by
analyzing their quantization tables, functions for storing this
quality and other JPEG settings in a parasite, and functions for
restoring these values.
* plug-ins/jpeg/jpeg-load.c (load_image): save the original JPEG
settings in a parasite after reading the JPEG header.
* plug-ins/jpeg/jpeg.c (run): restore the original JPEG settings
if they had been attached to a parasite and if they are better
than the defaults.
* plug-ins/jpeg/jpeg-save.c (save_image): added new type of
subsampling 1x2,1x1,1x1, which is useful for images with height >
width such as rotated images from some cameras.
(save_dialog): added hints about how the subsampling types can be
used, marked these strings as translatable.
* plug-ins/jpeg/jpegqual.c: new utility to report the quality
settings and sampling factors of existing JPEG files.
