The wording was so insufficient that it made people think it's a fatal
error, and subsequently made them suspicious because it seemed like the
fatal error is ignored.
Like the Deg / Rad classes, these are for strongly-typed representation
of time. Because the current way, either with untyped and imprecise
Float, or the insanely-hard-to-use and bloated std::chrono::nanoseconds,
was just too crappy.
This is just the types alone, corresponding typedefs in the root
namespace, and conversion from std::chrono. Using these in the Animation
library, in Timeline, in DebugTools::FrameProfiler, GL::TimeQuery etc.,
will eventually and gradually follow.
Same as the corresponding Corrade change. Should make
MAGNUM_BUILD_STATIC_UNIQUE_GLOBALS working also in cases where Magnum is
linked to just DLLs but not the main application executable. Such as
various plugins or native Python modules.
It isn't a nice UX to force users to hardcode a DLL name of their own
application when building a *dependency library*, but is a simple enough
middle ground between global symbol deduplication not working at all and
having to loop through all possible DLLs with EnumProcessModules() until
a symbol is found.
Most of the testing scaffolding here is a preparation for the actually
complex formats like BC6/7 or ASTC. Also, it's great to be able to use
Magnum from Python to prepare data for testing the C++ Magnum APIs.
Currently contains just one very silly Phong->PBR conversion utility,
but eventually it'll provide tools for simplifying, merging and
deduplicating materials.
With the intention that those will eventually contain also things like
YUp / YDown, PremultipliedAlpha and such.
This commit is mostly just busywork, wiring this into [Compressed]Image,
[Compressed]ImageView and Trade::ImageData and ensuring the flags get
correctly propagated during moves and conversions. Unfortunately in case
of Trade::ImageData it meant deprecating the current set of constructor
in order to insert an ImageFlags parameter before the importer state
pointer.
The only non-trivial piece of logic is when a 2D
[Compressed]ImageView gets converted to a 3D one, then the Array bit is
implicitly dropped, as 2D arrays of 1D images are not really a thing.
Instead, it's now possible to add new flags when doing the conversion --
for example to turn a 2D image to a (single-layer) 2D array image.
Similar to the change done in Corrade, see the commit for details:
878624ac36
Wow, this is probably the most backwards-compatibility code I've ever
written. Can't wait until I can drop all that.
It limits the support for CMake 3.12+, but it's much less verbose and I
don't expect people to use ancient CMake versions with IDEs like Xcode
or VS anyway, so this should be fine.
Its only use was for specifying N-dimensional SamplerWrapping because,
compared to a Math::Vector, it had an implicit constructor from a single
value (whereas the Vector has it explicit). I solved that by simply
adding a few single-value overloads where it mattered. There, done. No
need for this weird thing and confusion with Containers::Array anymore.
All places that used it now use Math::VectorN<SamplerWrapping>, but the
class is still included for backwards compatibility purposes, together
with providing implicit conversion from and to a Vector.
This deliberately doesn't follow the PixelFormat enum naming, as RGBA
components make no sense for most vertex data. Checking Metal and
WebGPU, they seem to have arrived at a similar conclusion, only VkFormat
is an outlier.
Instead of prefixing every value with (Compressed)PixelFormat::,
printing that just once. Also moved the name table to an external header
so it can be used later for configuration value parsing. Compared to
the previous commit, Bloaty reports a save, meaning these two commits in
total save about 4 kB:

Well. Bloaty reports a 0.3% increase in Debug and 0.1% in Release, but I
guess if the enums would be larger, the savings would be actually
significant.
This makes it possible to:
- finally use Magnum as a CMake subproject on Windows and have your
executables not fail to run with a "DLL missing" error (and the
setting is put to cache so superprojects just implicitly make use of
that)
- run tests on Windows without having to install first
- use dynamic plugins from a CMake subproject on any platform without
having to install first or load them by filename --- and the plugin
directory is now easily discovered as relative to
libraryLocation() of the library implementing given plugin interface
Deprecated for 2018.04, it's been almost a year since. Whoever is using
Magnum regularly updated already, and who not can always upgrade
gradually (2018.02, 2018.04, 2018.10, 2019.01 etc.).
It'll get used outside of the root namespace and since the callbacks tend
to be quite complex, it would be silly to require users to implement one
callback for Trade, one for Text and one for Audio, for example.
Will be used to supply general desired interpolation method to tracks to
make it possible for the user to decide about a particular interpolator
function for given type.
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.
