This function provides a wrapper around the IMG_idct_8x8_12q4       
function.  It reads 12Q0 values in from the input array, and        
writes them back as 12Q4.  Once all the values have been adjusted,  
the function then branches directly to IMG_idct_8x8_12q4.           
                                                                    
It is strongly recommended that you adapt your code to call         
IMG_idct_8x8_12q4 directly.  Calling this wrapper adds an extra     
16 cycles per block of processing overhead, as well as 116          
bytes of additional code.
