Process TKIND_ALIAS in SLTG typelibs, 0x14 in the tail is the 

tdescAlias.vt entry.
Added a small handler for TKIND_DISPATCH in SLTG.
ITypeLib_Release can have a NULL pointer as ITypeInfo*.
Split out _copy_arg function for both DispCall and ITypeInfo_fnInvoke,
added some more functionality.
ITypeInfo_fnInvoke can handle VT_USERDEFINED variants.
