Sorry, my commit auto-closed this PR by accident. Yes, the feature completeness sounds good,must have tests and ideally with docs.

> yes, rendering text, loading from fonts, text color, text position etc. GIL is not a rendering library. You should look at https://github.com/cpp-io2d/P0267_RefImpl and http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p0267r10.pdf, and plenty of other libraries...

Thanks for the example. For the competency test it looks good. For submission to GIL as example, it needs copyright notice, Jamfile/CMakeLists.txt update, some formatting (even minimal using the [.clang-format](https://github.com/boostorg/gil/tree/develop/example/clang-format)),...

@Sayan-Chaudhuri I believe we have discussed the initial issues pointed out by @lpranam above during review of https://github.com/boostorg/gil/pull/597#pullrequestreview-639138013 Please, try to avoid similar issues over and over again. This will...

This needs to be checked after #230 has been merged

I agree with your points @marco-langer I also was wondering about the actual redundancy of the `std::copy` thing. Let's postpone it after 1.80 is out - it's already too late...

So, I made similar observation while compiling `variant=release` (aka `-O3`) for the `test/pixel.cpp`, but this time the very same `channel.hpp:441:79` warning is giving up more details: ``` $ toolset=gcc-7 cxxflags="-std=c++11"...

@chhenning I've been trying smaller extracts from the failing test but none seem to reproduce the problem. Seems like it's the kind of [added cout and works](https://github.com/boostorg/gil/pull/50#issuecomment-376966346) mystery. ----- @stefanseefeld...

@chhenning during local testing I tried all sorts of switches, optimisation levels, with and without strict aliasing etc. On CircleCI all builds are using the same switches as defined in...

@chhenning No good news yet on the checksum bug from me, it still is failing on VS2017 64bit release build, see the AppVeyor. Got busy with the bitsN refactoring and...
