* All signatures may contain pointers into the input shader, and should only
* be accessed while the input shader remains valid.
*
* Signature elements are synthesized from legacy Direct3D bytecode as follows:
* - The \ref vkd3d_shader_signature_element.semantic_name field is set to an
* uppercase string corresponding to the HLSL name for the usage, e.g.
* "POSITION", "BLENDWEIGHT", "COLOR", "PSIZE", etc.
* - The \ref vkd3d_shader_signature_element.semantic_index field is set to the
* usage index.
* - The \ref vkd3d_shader_signature_element.stream_index is always 0.
*
* Signature elements are synthesized for any input or output register declared
* or used in a legacy Direct3D bytecode shader, including the following:
* - Shader model 1 and 2 colour and texture coordinate registers.
* - The shader model 1 pixel shader output register.
* - Shader model 1 and 2 vertex shader output registers (position, fog, and
* point size).
* - Shader model 3 pixel shader system value input registers (pixel position
* and face).
