Instead of the darkening of the hole as you suggested, I thought a less 
CPU intensive thing to do would be to keep the hole colmap cutter smooth 
but roughen the edges of the hole gfx cutter.

OK, code wise it isn't as straightforward as that.  But hopefully you get 
the idea.

With regards to the idea for getting rid of the lip/ledge at the bottom of 
the hole by making the bottom of the hole curve outwards.  I think there 
are problems with this idea.  The following are a few situations that 
could happen (left is without hole, right is with).


(1)                     |    |
                        |    |
         ________       |    |_____
        |               |
        |               |
    ____|           ____|


(2) \          /     \    |    |   /
     \        /       \   |    |  /
      \      /         \  |    | /
       \    /           \ |    |/
        \  /             \|
         \/

(3) |            |    |   |     |  |
    |            |    |   |     |  |
    |     /\     |    |   |     |  |
    |    /  \    |    |   |     |  |
    |   /    \   |    |   /     |  |
    |  /      \  |    |  /      \  |
    | /        \ |    | /        \ |
    |/          \|    |/          \|


Also, you've got to consider that the above situations are just fixed 
angles.  The angle between the vertical of the hole and the bottom corners 
of the hole can be anything at all.

As you suggested, I'll leave this digger stuff for now.

Thanks,
