// D3DXFX_DONOTSAVESTATE
//   This flag is used as a parameter to ID3DXEffect::Begin().  When this flag
//   is specified, device state is not saved or restored in Begin/End.
// D3DXFX_DONOTSAVESHADERSTATE
//   This flag is used as a parameter to ID3DXEffect::Begin().  When this flag
//   is specified, shader device state is not saved or restored in Begin/End.
//   This includes pixel/vertex shaders and shader constants
// D3DXFX_DONOTSAVESAMPLERSTATE
//   This flag is used as a parameter to ID3DXEffect::Begin(). When this flag
//   is specified, sampler device state is not saved or restored in Begin/End.
// D3DXFX_NOT_CLONEABLE
//   This flag is used as a parameter to the D3DXCreateEffect family of APIs.
//   When this flag is specified, the effect will be non-cloneable and will not
//   contain any shader binary data.
//   Furthermore, GetPassDesc will not return shader function pointers. 
//   Setting this flag reduces effect memory usage by about 50%.

//   Indicates that the value of this parameter can be treated as literal.
//   Literal parameters can be marked when the effect is compiled, and their
//   cannot be changed after the effect is compiled.  Shared parameters cannot
