// D3D10SHADER flags:
// -----------------
// D3D10_SHADER_DEBUG
// Insert debug file/line/type/symbol information.
//
// D3D10_SHADER_SKIP_VALIDATION
// 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.
//
// D3D10_SHADER_SKIP_OPTIMIZATION
// 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.
//
// D3D10_SHADER_PACK_MATRIX_ROW_MAJOR
// Unless explicitly specified, matrices will be packed in row-major order
// on input and output from the shader.
//
// D3D10_SHADER_PACK_MATRIX_COLUMN_MAJOR
// 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.
//
// D3D10_SHADER_PARTIAL_PRECISION
// Force all computations in resulting shader to occur at partial precision.
// This may result in faster evaluation of shaders on some hardware.
//
// D3D10_SHADER_FORCE_VS_SOFTWARE_NO_OPT
// Force compiler to compile against the next highest available software
// target for vertex shaders. This flag also turns optimizations off,
// and debugging on.
//
// D3D10_SHADER_FORCE_PS_SOFTWARE_NO_OPT
// Force compiler to compile against the next highest available software
// target for pixel shaders. This flag also turns optimizations off,
// and debugging on.
//
// D3D10_SHADER_NO_PRESHADER
// Disables Preshaders. Using this flag will cause the compiler to not
// pull out static expression for evaluation on the host cpu
//
// D3D10_SHADER_AVOID_FLOW_CONTROL
// Hint compiler to avoid flow-control constructs where possible.
//
// D3D10_SHADER_PREFER_FLOW_CONTROL
// Hint compiler to prefer flow-control constructs where possible.
//
// D3D10_SHADER_ENABLE_STRICTNESS
// By default, the HLSL/Effect compilers are not strict on deprecated syntax.
// Specifying this flag enables the strict mode. Deprecated syntax may be
// removed in a future release, and enabling syntax is a good way to make sure
// your shaders comply to the latest spec.
//
// D3D10_SHADER_ENABLE_BACKWARDS_COMPATIBILITY
// This enables older shaders to compile to 4_0 targets.
