0b050f4046 deprecate thumbnail auto_rotate, add no_rotate 
the auto_rotate option of thumbnail was default TRUE which made it
useless from the CLI, since GOption only allows --switch, not
--switch=false

deprecate auto_rotate, add no_rotate, but allow either to be used

502a3133a2 fix up vips_image_dump() 
it was still expecting standard libvips enums to be stored as ints ...
this helps im_printdesc as well

883facb1c0 better handling of flip in autorot 
if the orientation is one of the ones we don't handle (ie. there's a
flip as well as a rot), don't wipe the header tag
