Similarly to pixel formats, there is now generic Magnum::MeshPrimitive
and Magnum::MeshIndexType, which is convertible to GL::MeshPrimitive and
GL::MeshIndexType using GL::meshPrimitive() and GL::meshIndexType(). In
addition, the following is done:
* The original GL::Mesh::IndexType is now GL::MeshIndexType, original
name is now just a typedef.
* GL::Mesh::indexSize() is deprecated in favor of
Magnum::meshIndexTypeSize() and GL::Mesh::indexTypeSize().
* New GL::Mesh::indexType() and GL::MeshView::mesh() getters (not sure
why they were omitted)
* GL::Mesh::indexType(), GL::Mesh::indexTypeSize(),
GL::MeshView::setIndexRange() now expect that the mesh is indexed
(useful property in my opinion, also avoids getting random results).
* The extra MeshPrimitive::LinesAdjacency etc. are still present for
backwards compatibility, but marked as deprecated. Use
GL::MeshPrimitive values instead.
At the moment just the GL library itself w/o the tests, and without
backwards compatibility aliases. The following types were left in the
root namespace, despite being in the GL/ directory, as they will get
moved back soon:
* Image, CompressedImage and their dimensional typedefs
* ImageView, CompressedImageView and their dimensional typedefs
* PixelStorage
Not PixelFormat etc., that one will stay in the GL namespace and a
completely new PixelFormat enum will be provided in the root namespace.
More consistent with what's done elsewhere, reduces header dependencies,
allows me to (later) make this independent on the AL library and also
works around a Doxygen bug. Win win!
The current testing workflow had quite a few major flaws and it was no
longer possible after the move of Any* plugins to core. Among the flaws
is:
* Every plugin was basically built twice, once as the real plugin and
once as a static testing library. Most of the build shared common
object files, but nevertheless it inflated build times and made the
buildsystem extremely complex.
* Because the actual plugin binary was never actually loaded during the
test, it couldn't spot problems like:
- undefined references
- errors in metadata files
- mismatched plugin interface/version, missing entry points
- broken static plugin import files
* Tests that made use of independent plugins (such as TgaImageConverter
test using TgaImporter to verify the output) had a hardcoded
dependency on such plugins, making a minimal setup very hard.
* Dynamic loading of plugins from the Any* proxies was always directed
to the install location on the filesystem with no possibility to
load these directly from the build tree. That caused random ABI
mismatch crashes, or, on the other hand, if no plugins were
installed, particular portions of the codebase weren't tested at all.
Now the workflow is the following:
* Every plugin is built exactly once, either as dynamic or as static.
* The test always loads it via the plugin manager. If it's dynamic,
it's loaded straight from the build directory; if it's static, it
gets linked to the test executable directly.
* Plugins used indirectly are always served from the build directory
(if enabled) to ensure reproducibility and independence on what's
installed on the filesystem. Missing presence of these plugins causes
particular tests to be simply skipped.
* Plugins that have extensive tests for internal functionality that's
not exposed through the plugin interface are still built in two
parts, but the internal tests are simply consuming the OBJECT files
directly instead of linking to a static library.
Too much burden to implement. Nope. Sorry. All APIs were just asserting
that it's not enabled at the moment, so I may as well just remove it
completely.
Statically built plugins get imported automatically when using CMake 3.1
and newer. Otherwise simply #include a corresponding
importStaticPlugin.cpp file.

Proofread everything, make the packages the first choice (and manual
build only as a backup catch-all solution), don't force the users to
CMake but provide useful snippets to show how to use the libs from
CMake.
And removing the bundled std::optional implementation. This finally
makes this library compatible with C++17. Since this would be a huge
backwards-incompatible change that would make everyone angry, the
following had to be done in case both CORRADE_BUILD_DEPRECATED and
MAGNUM_BUILD_DEPRECATED is defined:
* Under C++11 and C++14, Containers::Optional / Containers::NullOpt is
aliased to std::optional / std::nullopt. This is no worse than the
state before, when we also provided these symbols.
* Under C++17, where standard <optional> header is available,
Containers::Optional provides implicit conversion to it. Only one-way
conversion is supported, as there was fortunately no Magnum API that
took std::optional via parameter, and there might be some corner
cases that this doesn't cover. The goal is to have all examples
compiling with the old API, at least.
* There's a new test especially for this, which checks that both the
C++11 and C++17 ways of doing things work as they should.
The typedef and conversion is marked as deprecated, so it will spit out
many warnings to push users to upgrade. I hope I can completely remove
this mess soon :/
