I was just wondering how this could be done with just one gfx cutter.  I 
suppose you could load it in as a CL_SurfaceProvider then create a Canvas 
for each one pixel high line in the gfx cutter.  The Canvases are then 
converted into Surfaces.

After a Digger has dug the "first" pixel, the first line of the gfx cutter 
is used.  After the "second" pixel is dug, the second line of the gfx 
cutter is used and so on.

Unfortunately, CL_SurfaceProvider is needed because in is the only 
practical way of going through a "surface" pixel by pixel (using 
get_pixel).

Is it worth doing this, or is it better (if still annoying) to have a 
"sprite" being the cutter with the first frame being 1 pixel high, the 
second frame being 2 pixels high, and so on?  Obviously the pixels in the 
first frame have to match those in the second etc...

Thanks,
Gervase.
