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.
Makes it possible to properly compute offset when adding matrix
attributes to mesh. The matrix-related test cases in Mesh test are now
passing. The vector count is now enum value to make it more clear that
that is compile-time constant independent of what was said in
constructor.
Remaining unspecified components are set to 0, 0, 1, according to spec.
Also cleaned up and simplified the internals, added debug output
operators for attribute component count and types and tested the whole
thing.
