Applying Post-Proccessing to the client

How do I apply pp to the client, I want to alter, brightness, colors, material overlays, and sharpen. Without console commands (Big order, hope fp can server it! :O)

Use DrawColorModify() for colormod, DrawSharpen() for sharpness, and DrawMaterialOverlay() for the material. Put these in the hook RenderScreenspaceEffects.
