// D3DXSHADER flags:
// -----------------
// D3DXSHADER_DEBUG
//   Insert debug file/line/type/symbol information.
//
// D3DXSHADER_SKIPVALIDATION
//   Do not validate the generated code against known capabilities and
//   constraints.  This option is only recommended when compiling shaders
//   you KNOW will work.  (ie. have compiled before without this option.)
//   Shaders are always validated by D3D before they are set to the device.
//
// D3DXSHADER_SKIPOPTIMIZATION (valid for D3DXCompileShader calls only)
//   Instructs the compiler to skip optimization steps during code generation.
//   Unless you are trying to isolate a problem in your code, and suspect the
//   compiler, using this option is not recommended.
//
// D3DXSHADER_PACKMATRIX_ROWMAJOR
//   Unless explicitly specified, matrices will be packed in row-major order
//   on input and output from the shader.
//
// D3DXSHADER_PACKMATRIX_COLUMNMAJOR
//   Unless explicitly specified, matrices will be packed in column-major 
//   order on input and output from the shader.  This is generally more 
//   efficient, since it allows vector-matrix multiplication to be performed
//   using a series of dot-products.
