Improve utilities sending channels, pixels and other GIL objects to
output stream for logging of test errors.
Fix missing namespace qualification in IO tests.
Comment TARGA test case with FIXME that was accidentally
uncommented in cc64bdd1a4
Motivation is to:
- use on simpler and light test framework,
- eliminate dependency on libraries like Boost.MPL,
- achieve faster compilation times for CI builds (20% seems feasible)
- have test programs easy to run and debug
- avoid macros
Remove outdated FIXME-s for bugs that have been already fixed.
Fix off-by-one bug in test/core/test_fixture.hpp generators.
Minor corrections and tidying up.
Add missing test assertions to numeric extension tests.
Fixes#458
Split header tests accordingly i.e. test core headers as part of
core tests, numeric extension headers as part of numeric tests, etc.
It extends the convention of sub-directories already established in
`include/boost/gil` directory. It is sensible to follow it in other
areas of the source tree (i.e. `test/`, `doc/` and `benchmark/`).
Another important reason to move the tests is to enable removal of
the top-level `Jamfile` with all its definitions of test-specific
requirements.
The top-level `Jamfile` is not advised, especially if it specifies
build requirements like C++ language version.
Those affect non-tests builds e.g. documentation, causing failures
during generation of HTML documentation (leads to missing docs).
