/**
 * 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.
