Sure, that is what the 0xd and 0xf do.
#define QC_YOFF         0x0d
#define QC_XOFF         0x0f
  
sendcmd(QC_YOFF, yoff);
sendcmd(QC_XOFF, xoff/4);

The y offset is in lines, the x offset in the usual multiples of 4.
A while ago, I sent the patches for this to Paul Chinn, with a function that 
tries to keep the image centred.  I don't know if he has chosen to incorporate 
them in his next release or not.
