-	IASIOThiscallResolver.cpp see the comments in iasiothiscallresolver.h for
-    the top level description - this comment describes the technical details of
-    the implementation.

-    BACKGROUND
-
-    The IASIO interface declared in the Steinberg ASIO 2 SDK declares
-    functions with no explicit calling convention. This causes MSVC++ to default
-    to using the thiscall convention, which is a proprietary convention not
-    implemented by some non-microsoft compilers - notably borland BCC,
-    C++Builder, and gcc. MSVC++ is the defacto standard compiler used by
-    Steinberg. As a result of this situation, the ASIO sdk will compile with
-    any compiler, however attempting to execute the compiled code will cause a
-    crash due to different default calling conventions on non-Microsoft
-    compilers.
-
-    IASIOThiscallResolver solves the problem by providing an adapter class that
-    delegates to the IASIO interface using the correct calling convention
-    (thiscall). Due to the lack of support for thiscall in the Borland and GCC
-    compilers, the calls have been implemented in assembly language.
-
-    A number of macros are defined for thiscall function calls with different
-    numbers of parameters, with and without return values - it may be possible
-    to modify the format of these macros to make them work with other inline
-    assemblers.
-
-
-    THISCALL DEFINITION
-
-    A number of definitions of the thiscall calling convention are floating
-    around the internet. The following definition has been validated against
-    output from the MSVC++ compiler:
-
-    For non-vararg functions, thiscall works as follows: the object (this)
-    pointer is passed in ECX. All arguments are passed on the stack in
-    right to left order. The return value is placed in EAX. The callee
-    clears the passed arguments from the stack.
-
-
-    FINDING FUNCTION POINTERS FROM AN IASIO POINTER
-
-    The first field of a COM object is a pointer to its vtble. Thus a pointer
-    to an object implementing the IASIO interface also points to a pointer to
-    that object's vtbl. The vtble is a table of function pointers for all of
-    the virtual functions exposed by the implemented interfaces.
-
-    If we consider a variable declared as a pointer to IASO:
-
-    IASIO *theAsioDriver
-
-    theAsioDriver points to:
-
-    object implementing IASIO
-    {
-        IASIOvtbl *vtbl
-        other data
-    }
-
-    in other words, theAsioDriver points to a pointer to an IASIOvtbl
-
-    vtbl points to a table of function pointers:
-
-    IASIOvtbl ( interface IASIO : public IUnknown )
-    {
-    (IUnknown functions)
-    0   virtual HRESULT STDMETHODCALLTYPE (*QueryInterface)(REFIID riid, void **ppv) = 0;
-    4   virtual ULONG STDMETHODCALLTYPE (*AddRef)() = 0;
-    8   virtual ULONG STDMETHODCALLTYPE (*Release)() = 0;      
-
-    (IASIO functions)
-    12	virtual ASIOBool (*init)(void *sysHandle) = 0;
-    16	virtual void (*getDriverName)(char *name) = 0;
-    20	virtual long (*getDriverVersion)() = 0;
-    24	virtual void (*getErrorMessage)(char *string) = 0;
-    28	virtual ASIOError (*start)() = 0;
-    32	virtual ASIOError (*stop)() = 0;
-    36	virtual ASIOError (*getChannels)(long *numInputChannels, long *numOutputChannels) = 0;
-    40	virtual ASIOError (*getLatencies)(long *inputLatency, long *outputLatency) = 0;
-    44	virtual ASIOError (*getBufferSize)(long *minSize, long *maxSize,
-            long *preferredSize, long *granularity) = 0;
-    48	virtual ASIOError (*canSampleRate)(ASIOSampleRate sampleRate) = 0;
-    52	virtual ASIOError (*getSampleRate)(ASIOSampleRate *sampleRate) = 0;
-    56	virtual ASIOError (*setSampleRate)(ASIOSampleRate sampleRate) = 0;
-    60	virtual ASIOError (*getClockSources)(ASIOClockSource *clocks, long *numSources) = 0;
-    64	virtual ASIOError (*setClockSource)(long reference) = 0;
-    68	virtual ASIOError (*getSamplePosition)(ASIOSamples *sPos, ASIOTimeStamp *tStamp) = 0;
-    72	virtual ASIOError (*getChannelInfo)(ASIOChannelInfo *info) = 0;
-    76	virtual ASIOError (*createBuffers)(ASIOBufferInfo *bufferInfos, long numChannels,
-            long bufferSize, ASIOCallbacks *callbacks) = 0;
-    80	virtual ASIOError (*disposeBuffers)() = 0;
-    84	virtual ASIOError (*controlPanel)() = 0;
-    88	virtual ASIOError (*future)(long selector,void *opt) = 0;
-    92	virtual ASIOError (*outputReady)() = 0;
-    };
-
-    The numbers in the left column show the byte offset of each function ptr
-    from the beginning of the vtbl. These numbers are used in the code below
-    to select different functions.
-
-    In order to find the address of a particular function, theAsioDriver
-    must first be dereferenced to find the value of the vtbl pointer:
-
-    mov     eax, theAsioDriver
-    mov     edx, [theAsioDriver]  // edx now points to vtbl[0]
-
-    Then an offset must be added to the vtbl pointer to select a
-    particular function, for example vtbl+44 points to the slot containing
-    a pointer to the getBufferSize function.
-
-    Finally vtbl+x must be dereferenced to obtain the value of the function
-    pointer stored in that address:
-
-    call    [edx+44]    // call the function pointed to by
-                        // the value in the getBufferSize field of the vtbl
-
-
-    SEE ALSO
-
-    Martin Fay's OpenASIO DLL at http://www.martinfay.com solves the same
-    problem by providing a new COM interface which wraps IASIO with an
-    interface that uses portable calling conventions. OpenASIO must be compiled
-    with MSVC, and requires that you ship the OpenASIO DLL with your
-    application.

-    ACKNOWLEDGEMENTS
-
-    Ross Bencina: worked out the thiscall details above, wrote the original
-    Borland asm macros, and a patch for asio.cpp (which is no longer needed).
-    Thanks to Martin Fay for introducing me to the issues discussed here,
-    and to Rene G. Ceballos for assisting with asm dumps from MSVC++.
-
-    Antti Silvast: converted the original calliasio to work with gcc and NASM
-    by implementing the asm code in a separate file.
-
-	Fraser Adams: modified the original calliasio containing the Borland inline
-    asm to add inline asm for gcc i.e. Intel syntax for Borland and AT&T syntax
-    for gcc. This seems a neater approach for gcc than to have a separate .asm
-    file and it means that we only need one version of the thiscall patch.
-
-    Fraser Adams: rewrote the original calliasio patch in the form of the
-    IASIOThiscallResolver class in order to avoid modifications to files from
-    the Steinberg SDK, which may have had potential licence issues.
-
-    Andrew Baldwin: contributed fixes for compatibility problems with more
-    recent versions of the gcc assembler.
