Bug#954177: libgegl-dev: gegl-sc-0.4 appears to be unusable

[Simon McVittie]

Package: libgegl-dev
Version: 0.4.22-1
Severity: normal

libgegl-dev and libgegl-0.4-0 contain a shared library libgegl-sc-0.4.so.0
and its pkg-config metadata.

However, libgegl-dev does not contain its development symlink
libgegl-sc-0.4.so (causing a Lintian warning), and does not contain
headers for the bundled poly2tri-c library that are included by the
<sc/sc-*.h> headers, which as far as I can see makes that shared library
impossible to depend on usefully.

If this library is useful and stable, gegl should ship everything
that is needed to use it, including the <poly2tri-c/**> headers (presumably
in /usr/include/gegl-0.4/poly2tri-c), or should depend on an external
poly2tri library separately packaged for Debian.

Or, if this library is unstable or not useful, gegl shouldn't ship it,
and certainly shouldn't ship its .pc file.

I don't know enough about gegl to make a useful decision on which of
those is correct, hence opening a bug instead.
