enblend-enfuse-4.2-bp153.2.1

- Add enblend-enfuse-4.2-gcc-10.patch: Fix build with GCC 10
  (picked from Gentoo, https://bugs.gentoo.org/723306).

- Add reproducibledate.patch to override build date (boo#1047218)
- Add reproducible.patch to override build hostname (boo#1084909)

- Update RPM groups.

- Switched to cmake build
  * Removed patch for autotools: enblend-latex-optional.patch
- Added enblend-enfuse-4.2-add-missing-cmakelists.patch
- Enabled support for OpenMP
- Enabled support for SSE2
- Turn on optimizations again
- Info pages are no longer available
- Added PDF documentation for enblend and enfuse

- use individual libboost-*-devel packages instead of boost-devel

- specify boost build dependendy version

- Update to version 4.2:
  + All deprecated options and features of version 4.1 have been
    removed.
  + Enblend and Enfuse support layer (aka "page", aka "frame")
    selection in of multi-layer image-files. This includes
    processing any layers in user-defined order.
  + Both Enblend and Enfuse can now perform all their pyramidal
    blending operations in CIELAB (aka L*a*b*, aka L-star) and
    CIELUV (aka L*u*v*) color spaces, too.
  + The new Graph-Cut algorithm is the default primary seam-line
    generator.
  + Avoid a division-by-zero in the Annealing Optimizer.
  + Fix a bug (sf#1356551) in the seam-line vectorization code that
    was there since 2004. The fix changes the position of almost
    any coarse-mask seam line vertex by one pixel.
  + Fix a longstanding quirk, which allowed to load masks into
    Enblend and Enfuse that were unsuitable for processing.
  + Fix a bug in the highlight-recovery that caused Enfuse to bail
    out with the uncaught exception "Minimizer1D::set_bracket:
    minimum not bracketed".
  + The OpenMP enabled versions of Enblend and Enfuse benefit from
    Google's TCMalloc library.
  + Several exposure weight functions were added to Enfuse. The
    choice is now up to the user. The default still is the Gauss
    function as in all Enfuse versions before.
- Add texlive-latex-bin-bin BuildRequires: new dependency.
- Drop use-default-gcc-inlining.diff: no longer needed.
- Add enblend-latex-optional.patch: Allow building without
  documentation, that is, make latex optional.
- Toggle _build_doc to 1: building documentation works again.

- Update to version 4.1.4
  * The introduction of additional blend color spaces in the Development
    Branch requires a new option to select them.    Here, in the Stable
    Branch, the new option `  *  * blend  * colorspace' just duplicates the
    functionality of `  *  * ciecam' and `  *  * no  * ciecam'.    The Stable Branch
    does *not* provide the additional blend colorspaces of the
    Development Branch.    The following equivalences hold
  * * ciecam         <=>      *  * blend  * colorspace=ciecam
  * * no  * ciecam    <=>      *  * blend  * colorspace=identity
    Both options `  *  * ciecam' and `  *  * no  * ciecam' are deprecated in 4.2 and
    will be withdrawn in 4.3.    Thus, users should prefer
    `  *  * blend  * colorspace'.
  * [Enblend and Enfuse] Fix the nesting  * depth counter for response
    files.    This bug prohibited to load more than 20 images in a single
    response file.
  * [Enblend and Enfuse] Allow grayscale images to bring their own
    (grayscale) profiles.    Previously grayscale images with ICC profiles
    were rejected.
  * [Enblend] Fix a possible domain error followed by a division  * by  * zero
    in the seam  * line optimizer.
  * [Enblend and Enfuse] Avoid an undeserved warning about incompatible
    colorspaces if they only disagree on their meta  * data (e.g. profile
    creation date/time).
  * [Enblend] Fix a bug in the Dijkstra Optimizer which could lead to
    undefined behavior in the placement of the (optimized) seam line.
  * [Enblend] Fix a non  * dereferencable vector iterator which led to a
    segfault.
  * [Enblend] Avoid a division  * by  * zero in the Annealing Optimizer.
  * [Enblend] Fix a bug (#1356551) in the seam  * line vectorization code
    that was there since 2004.    The fix changes the position of almost
    any coarse  * mask seam line vertex by one pixel.
- Update use-default-gcc-inlining.diff
- Add libICE-devel and pkg-config build dependencies

- Introduce _build_doc defines (currently set to 0): Allow to
  easily enable/disable the building of the documentation (incl.
  the reevant BuildRequires and file sections). Currently disabled,
  as enblend fails with texinfo 5.1; upstream is aware but there
  are multiple ways the texi files are broken (mainly using invalid
  characters for defintions).

- no more upstream tarball signatures, no need for gpg offline

- Update to patchlevel 3 of version 4.1:
  + Bug Fixes:
    [Enblend only] Fix problem of multiple, almost-identical
    seamlines that produce inexplicable black areas in the output
    panorama.
  + LCMS 2.5 is now required to build.

- update to patchlevel 2 of version 4.1:
  [Enblend and Enfuse] Fix a bug in the highlight-recovery that caused
  Enfuse to bail out with the uncaught exception
    "Minimizer1D::set_bracket: minimum not bracketed".
  This addresses LaunchPad Bug #1214004.
  [Enfuse] Clean up seemingly random, bright-colored pixels that
  sometimes show up when fusing images with high contrast and "large"
  color profiles.
  [Enblend only] Fix a race condition in the seam-line optimizer that
  can cause wrongly placed seams.
  [Enblend and Enfuse] Use a per-thread storage of all OpenMP
  Vigra-functors.  This avoids data races.
  [Enblend and Enfuse] The Boost implementation of the `Mersenne
  Twister' random number generator caused segmentation faults when
  used in the OpenMP-enabled versions of Enblend and Enfuse.  The new
  implementation is based on the GNU Scientific Library (GSL), which
  plays nicely with concurrent accesses.
  [Enblend only] Correct a mistake that causes overlapping images with
  multiple seams to be blended incorrectly.
  [Enblend only] Require the OpenGL extension
  `GL_ARB_texture_rectangle' for the `--gpu' option to work.  This
  does away with a pesky warning of OpenGL drivers that do support
  this extension and avoids crashes with drivers that don't.
  The GPU performance improvement of Enblend via `--gpu' now is only
  available with drivers that feature `GL_ARB_texture_rectangle'
  (among many other required OpenGL extensions).
  The OpenGL warning about odd texture sizes is unaffected by this
  change.
  [Enblend and Enfuse] Fix a longstanding quirk, which allowed to load
  masks that were unsuitable for processing.
- no more signed tar balls, droping gpg verification :/
- modified patches:
  * use-default-gcc-inlining.diff

- Added BuildRequire help2man to fix build with new automake

- Update to version 4.1 (bnc#800803):
  * All deprecated options since version 4.0 have been removed.
  * New primary seam-line generator.
  * Default to perceptual model of the difference image.
  * Parallelize CIECAM02 color conversion.
  * Enblend and Enfuse integrate seamlessly in color-managed
    workflow.
  * Require LittleCMS Version 2.x Unbounded CMM feature.
  * Option to assign different profiles to profile-free input images.
  * New gray-scale projector called "anti-value".
  * Enblend and Enfuse stop after saving all generated masks to
    files, if option "--save-masks" is given, but option "--output"
    is not.
  * Enblend and Enfuse can write output JPEG files with arithmetic
    JPEG compression and TIFF files with JPEG compression.
  * Enblend and Enfuse warn on images that alternate between with
    color profile and without.
  * Several new Commandline options: "--primary-seam-generator",
    "--image-difference", "--ciecam" (for -c) and --no-ciecam",
    "--fallback-profile=PROFILE", "--exposure-cutoff",
    "--load-masks", "--layer-selector", "--levels=auto".
  * Deprecated: "--smooth-difference", user-(re)sizable image-cache.
  * External Vigra version 1.8 or later is required.
  * Enblend no longer relies on libXMI.
- Verify GPG signature.

- workaround vigra bug where arithmetic coded JPEG is always
  created with libjpeg-turbo #bnc786566

- really build also with older libpng14

- build also with libpng15
  * libpng15.patch

- libjpeg-devel was missing in buildrequires.

- license update: GPL-2.0+
  No reason to believe the VIGRA license is used in aggregation. Use SPDX
  syntax

- add automake as buildrequire to avoid implicit dependency

- drop %_smp_mflags again, it takes too much resources

- Remove redundant/obsolete tags/sections from specfile
  (cf. packaging guidelines)
- Add missing make call
- Use %_smp_mflags for parallel build

- use original source

- licenses package is about to die
