I have commited the fix (I believe) and you were quite right.

well I can't see where you call setextent so here goes instead:
the offset of the layer is the placement of the tile with col,row=0,0
so if you crop(x,y,w,h) 150,65,200,500
the offset should be -150,-65 afterwards to move it to the topleft corner of 
the image.
