I've made some edits to simplify the wording of some comments, made sure
to not cause a rebuild of many packages, and pushed to master (staging
is currently frozen) as a second inkscape-1.0 package.

Thank you, I'm closing this.

Hello!

The following updates Inkscape to its 1.0 version.  The test suite is
enabled and an effort is made to unbundle as much of 3rd party libraries
as possible (but more can be done, if you'd like to help: see the
comments in the patch).

The last patch of the series (Add libdepixelize) is added as a WIP, and
is included as a curiosity only (not intended to be merged in its
current state).

Enjoy!

Maxim

+The build system now look for a system installed googletest or falls

+
+* CMakeLists.txt: Add call to find_package(GTest).
+(include_directories): Remove "src/googletest/googletest/include" from
+arg.
+* src/CMakeLists.txt[NOT GTEST_FOUND]: Define the gtest and gtest_main
+libraries when GTEST_FOUND is false.  Globally include the googletest
+headers here.  Define aliases for the gtest and gtest_main libraries
+that match those defined by the FindGTest module.
+* src/tests/CMakeLists.txt: Replace references to gtest_main and gtest
+by GTest::Main and GTest::GTest, respectively.

+Load data into a binary file using simple commands from the input.

+Sort, merge, search, retrieve or generate test data consisting of fixed size
+binary records.
+@item binreplace
+Find or find/replace in binary files.
+@item binsplit
+Split test data consisting of fixed size binary records into one or more
+output streams.

+Find changes between two files at the character level.  Unlike \"diff\", it

+Double precision interactive command line math calculator.

+A utility for rapid retrieval of text by line numbers, in any order, from a
+text file.
+@item mdump
+Format binary data.
+@item msgqueue
+Create message queues and send/receive messages.
+@item mbin
+@itemx mbout
+Multiple buffer in and out.  Used for buffering a lot of data between a slow
+device and a fast device.  Mostly for buffering streaming tape drives for use
+with slower network connections, so that streaming is maintained as much as
+possible to minimize wear on the tape device.

+Corrupt data streams - useful for testing error correction and data recovery.

+Filter, list, or split a tar file.

Subject: [PATCH 13/14] gnu: inkscape: Update to 1.0.

* gnu/packages/inkscape.scm (inkscape)[version]: Update to 1.0.
[origin]: Remove the obsolete Poppler patch.  Add a macro to remove bundled
libraries where possible.
[inputs]: Upgrade gtk+-2 and gtkmm-2 to their current version.  Add autotrace,
gdl-minimal, lib2geom, libjpeg and libsoup.  Upgrade python-2 to its current
version, and move it...
[native-inputs]: ...here.  Add imagemagick and googletest.
[arguments]: Enable tests, specifying the test target as "check".  Move the
check phase after the install phase.  Remove the obsoleted
adjust-for-new-poppler phase.  Add a set-home phase to quiet Inkscape
warnings.  Add a disable-latex-export-tests phase to skip failing tests.
[license]: Change to GPLv3+, although upstream says GPLv2+, due to an
unresolved license incompatibility when building with the external lib2geom
library.
* gnu/packages/patches/inkscape-poppler-0.76.patch: Delete file.
* gnu/local.mk: Unregister it.

Subject: [PATCH 14/14] gnu: WIP: Add libdepixelize.

WIP: This currently fails to build.  We need to figure out which ancient
version of lib2geom it needs to link against.

* gnu/packages/graphics.scm (libdepixelize): New variable.
