Option to switch between sample and bilinearsample

[Jefemy]

In the shader fragment functions it uses BilinearSample to get the color but I noticed that this causes extremely small differences in the output image. I am using this package to render something that has to be exactly the same on every output and I noticed that the Sample function does not have this problem.

Not exactly experienced with stuff like this but would it cause problems to include an option in the shader to switch between the sampling types so I don't have to save an edited version of the code with mine?
