Align with `subsampled_view` overloads accepting `point_t` and `coord_t`
Both types are based on `std::ptrdiff_t`. Fixes compilation warnings.
Tidy up `subimage_view` and `subsampled_view` with trailing return.
Add tests for `subimage_view` in core and dynamic_image extension.
(First tests for the dynamic_image, hurray! :))
Add explicit cast to double in division operator for point<T> to
fix compilation warnings.
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.
Although GCC 4.8 is labelled as C++11 compatible, the reasons are:
* GCC 4.8 is buggy enough to prevent reasonable use of Boost.MP11
* GCC 4.8 is dying
Closes#282
* It lives in channel/ directory, so the prefix is superfluous
* New name makes a convention for fixture headers for other test topics
Add missing and rename existing include guards.
Document maintenance rules of `test/legacy/` content.
Motivation to move the `test/legacy/` is to:
* clarify status of those tests
* make it easier to run tests selectively
* separate new/upcoming feature-specific tests
from those all-in-one tests.
Other changes:
Rename `gil_test_common.hpp` to `unit_test.hpp` to make
it clearer it acts as `boost/test/unit_test.hpp proxy`.
Remove `<include>$(BOOST_ROOT)` from `Jamfile`-s as unnecessary.
