Added basic test cases to verify that the line binner is creating tile properly for the basic case, the case where a line is too long and is removed, and when a line is too long and it's ends are drawn with a fade.
Added default calc pixel function to line binner's public processing methods and updated test cases accordingly.
Removing WIP code that shouldn't have been in the final check in.
