/**
* Native bindings to the NV_viewport_swizzle extension.
*
* This extension provides a new per-viewport swizzle that can modify the position of primitives sent to each viewport. New viewport swizzle state is
* added for each viewport, and a new position vector is computed for each vertex by selecting from and optionally negating any of the four components of
* the original position vector.
*
* This new viewport swizzle is useful for a number of algorithms, including single-pass cubemap rendering (broadcasting a primitive to multiple faces and
* reorienting the vertex position for each face) and voxel rasterization. The per-viewport component remapping and negation provided by the swizzle
* allows application code to re-orient three-dimensional geometry with a view along any of the X, Y, or Z axes. If a perspective projection and depth
* buffering is required, 1/W buffering should be used, as described in the single-pass cubemap rendering example in the "Issues" section below.
