Calling map<void>() was trying to instantiate ArrayView<void> through
arrayCast<void>(), which is not possible (void has no size etc etc.).
Casting the returned pointer directly instead. Thanks to @AndySomogyi
for pointing this out.
I introduced *strong* enum with values, in a subnamespace, that have the
same name as completely unrelated typedefs. Guess what?! It breaks ALL
LINKS TO THOSE TYPEDEFS! **EVERYWHERE!!!**
The change done in 680144f1c5 was not
properly handling these cases:
* Mesh(NoCreateT) and wrap() were not constructing the internal vector,
which blew up when move-assigning another instance.
* ~Mesh() was not destructing the internal vector if the VAO ID was
zero or non-owning wrap() was used.
Strangely enough none of these were causing *any* problems for me on
Linux (even ASan was totally quiet and due to the unfortunate
combination of bugs even when I assigned totally random data to the
storage vector). This however blew up on MSVC, assuming there the
implementation is more checked.
Because it's possible to construct Mesh with no GL context available,
the move construction and destruction needs to avoid accessing Context
unless really necessary (it would be also unclear which type of vector
should be constructed if we have no context).
Extended the tests to handle hopefully all the cases.
In particular, the AbstractTexture and AbstractQuery subclasses didn't
have that. I can't remember the rules about noexcept (and the users even
less), so let's make that explicit.
This allows moving Buffer instances without fear of breaking stuff. I
thought this was in since a long time, but doesn't seem so. This
reintroduces a header dependency, but until I have Containers::Storage
or something that *can* store forward-declared type safely, it's
inevitable.
This is actually a preparation to make buffer-owning meshes a
possibility (where I would need an union of vectors otherwise),
nevertheless it removes the dependency on a vector.
The Platform::*Application::Configuration class was split into
Configuration and GLConfiguration, the latter containing only
GL-specific configuration. Moreover, createContext() and
tryCreateContext() were renamed to create() / tryCreate().
There's now a constructor and a create() / tryCreate() overload taking
GLConfiguration and this will be later extended with VkConfiguration,
for example. GL-specific getters/setters from Configuration are now
marked as deprecated and merged into GLConfiguration during context
creation.
Everything has still hard dependency on GL, that will be done in the
next commits.
Was Magnum::GL::Extensions::GL before and the redundancy was completely
unnecessary. Potential future extensions coming from GLX, EGL or whatnot
will most probably be in the Platform namespace in a completely separate
file, so this is not a problem.
All code internal to the GL library is affected, not much the outside,
as that is handled by the compatibility alias.
The MAGNUM_ASSERT_VERSION_SUPPORTED(),
MAGNUM_ASSERT_EXTENSION_SUPPORTED(), MAGNUM_VERIFY_NO_ERROR() macros are
now MAGNUM_ASSERT_GL_VERSION_SUPPORTED(),
MAGNUM_ASSERT_GL_EXTENSION_SUPPORTED() and MAGNUM_VERIFY_NO_GL_ERROR().
Backwards-compatible aliases are in the original headers, as usual.
The Sampler class was split into GL::Sampler (which is now mostly just a
placeholder for implementing OpenGL sampler objects), pairs of generic /
GL-specific SamplerFormat / GL::SamplerFormat, SamplerMipmap /
GL::SamplerMipmap, SamplerWrapping / GL::SamplerWrapping enums and the
GL-specific GL::SamplerCompareMode, GL::SamplerCompareFunction,
GL::SamplerDepthStencilMode enums.
The old Sampler class is marked as deprecated and aliases its enum to
the generic enums (or to the GL-specific ones in case the generic
versions are not available).
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.
