 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)
%]
