// 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
// Instructs the compiler to skip optimization steps during code generation.
// Unless you are trying to isolate a problem in your code 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.
//
// D3DXSHADER_PARTIALPRECISION
// Force all computations in resulting shader to occur at partial precision.
// This may result in faster evaluation of shaders on some hardware.
//
// D3DXSHADER_FORCE_VS_SOFTWARE_NOOPT
// Force compiler to compile against the next highest available software
// target for vertex shaders. This flag also turns optimizations off,
// and debugging on.
//
// D3DXSHADER_FORCE_PS_SOFTWARE_NOOPT
// Force compiler to compile against the next highest available software
// target for pixel shaders. This flag also turns optimizations off,
// and debugging on.
//
// D3DXSHADER_NO_PRESHADER
// Disables Preshaders. Using this flag will cause the compiler to not
// pull out static expression for evaluation on the host cpu
//
// D3DXSHADER_AVOID_FLOW_CONTROL
// Hint compiler to avoid flow-control constructs where possible.
//
// D3DXSHADER_PREFER_FLOW_CONTROL
// Hint compiler to prefer flow-control constructs where possible.

//----------------------------------------------------------------------------
// D3DXCreateTextureShader:
// ------------------------
// Creates a texture shader object, given the compiled shader.
//
// Parameters
// pFunction
// Pointer to the function DWORD stream
// ppTextureShader
// Returns a ID3DXTextureShader object which can be used to procedurally
// fill the contents of a texture using the D3DXFillTextureTX functions.

//----------------------------------------------------------------------------
// D3DXPreprocessShader:
// ---------------------
// Runs the preprocessor on the specified shader or effect, but does
// not actually compile it. This is useful for evaluating the #includes
// and #defines in a shader and then emitting a reformatted token stream
// for debugging purposes or for generating a self-contained shader.
//
// Parameters:
// pSrcFile
// Source file name
// hSrcModule
// Module handle. if NULL, current module will be used
// pSrcResource
// Resource name in module
// pSrcData
// Pointer to source code
// SrcDataLen
// Size of source code, in bytes
// pDefines
// Optional NULL-terminated array of preprocessor macro definitions.
// pInclude
// Optional interface pointer to use for handling #include directives.
// If this parameter is NULL, #includes will be honored when assembling
// from file, and will error when assembling from resource or memory.
// ppShaderText
// Returns a buffer containing a single large string that represents
// the resulting formatted token stream
// ppErrorMsgs
// Returns a buffer containing a listing of errors and warnings that were
// encountered during assembly. If you are running in a debugger,
// these are the same messages you will see in your debug output.
