Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
Use AbstractFeature<dimensions, T>, AbstractGroupedFeature<...>,
AbstractFeatureGroup<...>, FeatureGroup<...> like before and add two
kinds of aliases instead of only one, one with *Basic* for abstract type
and one for Float type.
Partially reverts commit 572efce3f7.
Use AbstractObject<dimensions, T> like before and add two kinds of
aliases instead of only one:
AbstractBasicObject2D<T>/AbstractBasicObject3D<T> for abstract type and
AbstractObject2D/AbstractObject2D for Float.
Makes it easier to use AbstractObject in templates of fixed dimensions
(e.g. Bullet integration, where it can now be written as
`AbstractBasicObject2D<btScalar>` instead of potentially confusing
`AbstractBasicObject<2, btScalar>`).
Partially reverts commit cfd405c32c.
Calling functions directly on Object will result in non-virtual calls,
calling functions on AbstractObject will result in virtual calls. Also
removed now unneeded "hacks" like `sceneObject()` and properly hiding
unsafe functions taking `AbstractObject*` with safe functions taking
`Object*`. Also hide `isScene()` from public documentation, as it is
sort-of hack too.
Removed workarounds for alias templates, variadic templates and
anonymous enums, but 1.8.2 has some bug with forward declarations
causing classes to appear in default namespace, breaking
cross-references.
It prevents unwanted implicit conversions from e.g. nullptr to Camera,
Vector2 to Physics::Point etc. By making all the constructors explicit
it is easier to routinely add the keyword to all new classes instead of
thinking about cases when to add and when not to.
Using header with forward declarations, containing declarations for all
classes with default parameters. The classes themselves don't have the
defaults.
This also allows users to more conveniently forward-declare instead of
digging in sources and writing the declarations on their own.
The downside of this is that the functions are now virtual, which makes
them slower than before. Maybe final qualifier would help?
AbstractObject::sceneObject() is marked as private in Object to avoid
confusion.
Functionality present in Object is now split into three main components:
* Object itself, handling parent/children relationships
* Transformation implementation and interfaces for common functionality
* Object features, providing transformation caching and base for
cameras, collision shapes, rigid bodies etc.
Some functionality depending on former implementation is temporarily
disabled and will be reworked later.
