Started the code for a grid that knows how to handle itself.

The code for this item is a bit too big to be just the grid
of the dives and I know that, don't bully me. :)
The main idea of this grid is that it knows when it should be
updated. this is a bit different than the old code where all
the painting happened on the same method. This is bad because
it's more code, but it's better because if I break the grid,
only the grid will be broken, and it's easyer to spot the breakage.

in the old code if I did the wrong thing with the graphics context,
the whole graph gots messed out.
