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.
They aren't much useful in Math namespace and here it allows to handle
also Color3/Color4 types. Moreover all RGBA component names were removed
from Math namespace, so it would be inconsistent to have them there only
in swizzle() functions.
On the other hand everything of this is done at runtime, so it's less
performant than the previous version, mainly when used in loops. When
the result is declared as constexpr, it is done at compile time, just
like the previous version.
I don't know which version to keep, so there will be both until a good
decision.
