// 1. a wrapper of an UNO struct (the wrapper was created by this bridge)
// 2. a wrapper of an UNO interface (created by this bridge)
// 3. a dispatch object that implements UNO interfaces
// 4. a dispatch object.

// If the parameter "aType" has a value then the COM object ( pUnknown) is supposed to
// implement the interface described by "aType". Moreover it ( pUnknown) can implement
// several other
// UNO interfaces in which case it has to support the SUPPORTED_INTERFACES_PROP (see
// #define) property. That property contains all names of interfaces.
// "pUnknown" is wrapped by a COM wrapper object that implements XInvocation, e.g.
// IUnknownWrapper_Impl. Additionally an object of type "aType" is created by help
// of the INTERFACE_ADAPTER_FACTORY (see #define) service. The implementation of
// "aType" calls on the COM wrapper's XInvocation::invoke. If the COM object supports
// more then one UNO interfaces, as can be determined by the property
// SUPPORTED_INTERFACES_PROP, then the INTERFACE_ADAPTER_FACTORY creates an object that
// implements all these interfaces.
// This is only done if "pUnknown" is not already a UNO wrapper,
// that is it is actually NOT an UNO object that was converted to a COM object. If it is an
// UNO wrapper than the original UNO object is being extracted, queried for "aType" (if
// it is no struct) and returned.

// This function tries to the change the type of a value (contained in the Any)

// JavaScript passes integer values always as VT_I4. If there is a parameter or
// property of type any then the bridge converts the any's content according
// to "o2u_variantToAny". Because the VARTYPE is VT_I4 the value would be converted
// to TypeClass_LONG. Say the method XPropertySet::setPropertyValue( string name, any value)
// would be called on an object and the property actually is of TypeClass_SHORT.
// After conversion of the VARIANT parameter the Any would contain type
// TypeClass_LONG. Because the corereflection does not cast from long to short
// the "setPropertValue" would fail as the value has not the right type.

// The corereflection does convert small integer types to bigger types.
// Therefore we can reduce the type if possible and avoid the above mentioned
// problem.
