idLib contains stateless support classes and concrete types. Some classes
do have static variables, but such variables are initialized once and
read-only after initialization (they do not maintain a modifiable state).
The interface pointers idSys, idCommon, idCVarSystem and idFileSystem
should be set before using idLib. The pointers stored here should not
be used by any part of the engine except for idLib.
The frameNumber should be continuously set to the number of the current
frame if frame base memory logging is required.
