TBLUniqueId
Unique identifier that can be used for caching purposes.
Some objects such as TBLImage and TBLFontFace have assigned an unique identifier that can be used to identify such objects for caching purposes. This identifier is never zero, so zero can be safely used as "uncached".

Remarks
Unique identifier is per-process. It's implemented as an increasing global or thread-local counter in a way that identifiers would not collide.
