Correct calculation to correctly map CMYK 0 to minimum
and 1 to maximum of input and output channel types.
If float-point division is necessary, use double instead of float
which may be too narrow for large operands. cmyk32_pixel_t is based on
uint32_t which multiplication by its maximum may yield result too
large to fit 32-bit float.
For example, (uint32_t(c) - uint32_t(k)) * float(s) for
c = 4294967295, k = 0, s = 1.0
results in 4294967300 value which does not fit uint32_t.

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Remove outdated FIXME-s for bugs that have been already fixed.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
Since `std::uninitialized_fill` performs a placement new on each
element in the range, it is important to ensure core and packed
pixel types behave correctly.
Split general purpose test fixtures into core/test_fixture.hpp.
Refactoring to unify use of the common framework across GIL tests.
Merge `unit_test_utility.hpp` into `unit_test.hpp` for convenience.
Add several test cases to `gil::point` tests.
First stab at convolution tests includes cases with the identity kernel.
Move `pixel`-s streaming facility used by Boost.Test (required by
`BOOST_TEST` macro) to the common header for re-use in other tests.
Avoid Clang flooding with non-disableable warnings like:
T does not declare any constructor to initialize its non-modifiable members
when compiling with concepts check enabled.
Bug 41759: `warn_no_constructor_for_refconst` can not be disabled (Boost.ConceptCheck)

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).
