By looking at @timholy coverage results, I saw that Base.graphics is virtually untested. The module seems to be self-sustained, it does not seem to be used in Base or requiring any low level code implementation in Base. Therefore I think it is natural to implement it in a package in order to reduce Base according to #5155. The module seems to be used in the Color.jl package.

If could be removed it would be good to get the deprecation process going in 0.4
