Note -- since there are no visual tests for Phong yet, this is done in
the least intrusive manner to avoid breaking current functionality. It's
likely very underperforming due to the matric calculation per fragment,
it'll get optimized once I have proper tests.
Also move it to a new GenerateNormals.h header so we can easily add
generateSmoothNormals() to it. The old API and header is deprecated and
will be removed in the future. I can't be bothered rewriting the old
code using the new thing, so it's preserved there as a mausoleum until
it gets finally nuked from the orbit.
Provide a version taking StridedArrayView instead, taking an arbitrary
view and also arbitrary index type. Also introduce duplicateInto() which
doesn't even allocate, but rather writes the output to pre-existing
location.
Found while working on the Python bindings --- BoolVector4(0b1010) got
printed as BoolVector(0101), which is totally confusing. Now it prints
it in a way that looks exactly the same as when constructing the vector
with binary literals.
This fixes a conflicting definition of GLsizeiptr and GLintptr when
Magnum is combined with qopengl.h from Qt on Windows. Khronos has it as
`signed long int`, whereas qopengl.h as ptrdiff_t, which is just `int`.
Instead make use of the ArrayView STL compatibility. To avoid breaking
almost all existing code the Corrade/Containers/ArrayViewStl.h header is
included implicitly when MAGNUM_BUILD_DEPRECATED is defined, but this
will get removed in some future release to speed up the compilation.
The Audio::Extension::extensions() and GL::Extension::extensions()
functions now return an ArrayView instead of a reference to std::vector.
Having a function-local static std::vector is the worst thing ever. Ugh.
This allows us to get rid of the StaticArrayView, which is the last
roadblock on the way to a single-header math. The planes() are now
deprecated, along with the include, and will get removed in a future
release.
