Intend to transition openjpeg 1.5

[Mathieu Malaterre <malat@debian.org>]

Dear all,

  I would like to start working on the future openjpeg 1.5 transition.
openjpeg 1.5 has been uploaded to experimental:

https://buildd.debian.org/status/package.php?p=openjpeg&suite=experimental

  I would like to now `mass-bug` on all packages that build-dep on
libopenjpeg-dev, namely:

gpac
gmerlin-avdecoder
poppler
libav
blender
openslide
mupdf
ants
magics++
gdcm
koffice
freeimage
itksnap

  to warn those packagers on my intention.

  Would that be ok ?

Thanks,

-M
