Trying to use an interface that depends on GblBox as a property throws an error

[Haikuno]

X Type Mismatch: [GblVariant] Attempted to use type that doesn't implement IVariant.

The type validation doesn't seem to check for type dependencies?

So I fixed one aspect of this bullshit, which was the type-checker not being smart enough to know that an interface related to another interface through a dependency on a concrete type implementing the target interface is a valid cast...

I believe I have fixed that part, so the GblVariant error with the type mismatch should go away; however, I think once it becomes a GblVariant, it's still not type-compatible with a GblVariant of GblBox type, due to not knowing how to convert between the two.... I think I still need to investigate that side.
