The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
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.
Because we can't forward-declare class members we would need to include
whole Mesh (along with all OpenGL headers and other stuff) just to use
Primitive enum. The old Mesh::Primitive is now alias to new one, is
marked as deprecated and will be removed in future release.
The access methods assert that the user is querying only available data.
Also updated Primitives implementation to create MeshData when
everything is done, not creating empty MeshData and then shooting the
data through interface intended for end users.
Magnum.h now doesn't include anything except OpenGL headers, thus
changes in Math library don't trigger recompilation of everything, but
only of things really depending on it.
Math constants moved to separate file for similar reasons, de-inlined
some functions to remove the need for some #includes.
