Paint Dirt: some small fixes
- normalize → average the vector: the vector isn't normalized here, because
it doesn't necessarily becomes unit length. Instead, the sum is converted
to an average vector.
- angle is the acos()…: the dot product between the vertex normal and the
average direction of the connected vertices is computed, and not the
opposite.
- The initial `con` list was discarded immediately and replaced by a new
list.
- File didn't end with a newline.
