+@   GfxMultiplyAsm - Multiply a 16:16 fixed point factor into iValue.
+@
+@       This function multiplies a 16:16 fixed point factor into iValue using
+@   an ARM 64 bit multiply instruction.  This is much faster than using the
+@   Symbian TInt64 class.  Note that iValue MUST be the first data member of
+@   this class.
+@
+@       r0 = Pointer to iValue (First data item in TFixPt class).
+@       r1 = Second factor to multiply.
