* A mask of projected textures.

* When this parameter is provided to a shader model 1.0-1.3 pixel shader,

* component before sampling.
*
* The default value is zero, i.e. no textures are projected.
*
* The data type for this parameter must be
* VKD3D_SHADER_PARAMETER_DATA_TYPE_UINT32.

* Only VKD3D_SHADER_PARAMETER_TYPE_IMMEDIATE_CONSTANT is supported in this
* version of vkd3d-shader.
