C# Class Axiom.Graphics.AutoParamDataSource

This utility class is used to hold the information used to generate the matrices and other information required to automatically populate GpuProgramParameters.
This class exercises a lazy-update scheme in order to avoid having to update all the information a GpuProgramParameters class could possibly want all the time. It relies on the SceneManager to update it when the base data has changed, and will calculate concatenated matrices etc only when required, passing back precalculated matrices when they are requested more than once when the underlying information has not altered.
