What's left is *a lot* of places taking monstrous
std::vector<std::reference_wrapper> and that can't be changed to
std::vector<Containers::Reference> in a source-compatible way. Even that
would be only a temporary change, since the goal is to fully avoid
dependency on STL in those cases.
The final version of these APIs should take
Containers::ArrayView<Containers::Reference> and be implicitly
convertible froom e.g. std::vector<Containers::Reference>. That's
definitely possible, but not in time for 2019.01, so instead of forcing
users to temporary pass a `{vec.begin(), vec.size()}` everywhere instead
of just `vec`, I'm rather keeping these APIs intact.
Much easier to write (and explain!) than Shaders::VertexColor2D::Color{
Shaders::VertexColor2D::Color::Components::Three}. Ugh. Why again it
took me *years* to realize?
It was returning either pixel size or compressed block size, which is
now available directly via other means.
This is a breaking change, but I don't expect these functions to be
used widely beyond Magnum internals.
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.
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.
All functionality is now available through free functions. The classes
are now just deprecated wrappers and/or typedefs and will be removed in
some future release.
Followup to previous commit -- links to opengl.org are now redirected to
khronos.org and the extension links have the same format for both GL and
GLES. That allows me to remove some of the Doxygen aliases and use just
a single set of the functions for both GL and GLES.
It was just RGB before. In order to avoid breaking current code, the
attribute now requires explicit specification of number of components.
If building with deprecated APIs enabled, there is an additional
deprecated constructor that defaults to RGB so the current code should
keep working as-is.
There will be numerous additions to this one so it made sense to make it
a static library instead of a header-only library. That also allows
CMake users to just link to Magnum::OpenGLTester instead of going
through the pain of a huge branching in order to find a correct
windowless application just to run their tests. It could have been done
even without the static library using a INTERFACE target, but that
wouldn't work on CMake < 3.0 (which, unfortunately, quite a few people
are still stuck with).
Unfortunately it's already heavily used elsewhere so I had to go through
the pain of deprecating the old implementation. The old implementation
was header-only so it can't be just typedef'd to the new one as there
would be linker failures. So the old header is just kept as it was, with
only the macros reduced.
