Sampler is the base of all texture samplers. Texture samplers encapsulate
a texture reference with a set of states that define how the texture
gets applied to a surface. Sampler states are set either via Params defined
on the Sampler object or directly via one the convenience methods defined
on the Sampler. The following states are supported (default values are in
parenthesis):
\li 'addressModeU' (WRAP)
\li 'addressModeV' (WRAP)
\li 'addressModeW' (WRAP)
\li 'magFilter' (LINEAR)
\li 'minFilter' (LINEAR)
\li 'mipFilter' (POINT)
\li 'borderColor' ([0,0,0,0])
\li 'maxAnisotropy' (1)
