-2.2  Keywords
--------------
-
-
-  discard           Discard fragment.
-
-  dst               First destination register.
-
-  dst0              First destination register.

-
-3  Other tokens
-===============
-
-
-3.1  Declaration Semantic
--------------------------
-
-
-  Follows Declaration token if Semantic bit is set.
-
-  Since its purpose is to link a shader with other stages of the pipeline,
-  it is valid to follow only those Declaration tokens that declare a register
-  either in INPUT or OUTPUT file.
-
-  SemanticName field contains the semantic name of the register being declared.
-  There is no default value.
-
-  SemanticIndex is an optional subscript that can be used to distinguish
-  different register declarations with the same semantic name. The default value
-  is 0.
-
-  The meanings of the individual semantic names are explained in the following
-  sections.
-
-
-3.1.1  FACE
-
-  Valid only in a fragment shader INPUT declaration.
-
-  FACE.x is negative when the primitive is back facing. FACE.x is positive
-  when the primitive is front facing.
