Message:

Moved the singleton creation/destruction mess to the Core class by using just two possible Scopes:

• ScopeID::Root for singletons that may always persists
• ScopeID::Graphics for singletons that only work when graphics was loaded

File:

• code/branches/core5/src/libraries/util/Scope.h (modified) (4 diffs)
