tiff/tiff-visibility.patch
OBS User mrdocs 0c5e91f27a Accepting request 99532 from home:elvigia:branches:graphics
- remove libjpeg-devel and zlib-devel from libtiff-devel
  requires as they are _not_ required to use the library.
  Now, this _will_ break packages with wrong buildrequires
  for good.

- Hide private symbols using gcc visibility, this has been
  applied only to functions that the source code clearly states
  that are internal to the library.
- Run spec cleaner
