This is a special class object that holds a handle to the sampler state object given by the graphics back-end for a particular combination of texture sampling settings.
Some graphics back-ends (like OpenGL) use mutable sampler objects, whereas others (Direct3D 10+) use immutable ones. In Panda3D, each unique sampler state has its own SamplerContext, which simplifies the implementation and makes redundant sampler objects impossible.
