This expands the interface of 'CustomResourceManager' to get a Material for post processing a frame buffer (currently EFB). The flow is similar to the normal draw material but distinguishes itself by not needing a UID. The full shader is much simpler than the draw shader and is currently put inline with the shader resource.
