/**
 * Native bindings to the ARB_seamless_cube_map extension.
 * 
 * When sampling from cube map textures, a three-dimensional texture coordinate is used to select one of the cube map faces and generate a two dimensional
 * texture coordinate ( s t ), at which a texel is sampled from the determined face of the cube map texture. Each face of the texture is treated as an
 * independent two-dimensional texture, and the generated ( s t ) coordinate is subjected to the same clamping and wrapping rules as for any other two
 * dimensional texture fetch.
 * 
 * Although it is unlikely that the generated ( s t ) coordinate lies significantly outside the determined cube map face, it is often the case that the
 * locations of the individual elements required during a linear sampling do not lie within the determined face, and their coordinates will therefore be
 * modified by the selected clamping and wrapping rules. This often has the effect of producing seams or other discontinuities in the sampled texture.
 * 
 * This extension allows implementations to take samples from adjacent cube map faces, providing the ability to create seamless cube maps.
 * 
 * Promoted to core in {@link GL32 OpenGL 3.2}.
