/**
 * Native bindings to the ARB_texture_border_clamp extension.
 * 
 * The base OpenGL provides clamping such that the texture coordinates are limited to exactly the range [0,1]. When a texture coordinate is clamped using
 * this algorithm, the texture sampling filter straddles the edge of the texture image, taking 1/2 its sample values from within the texture image, and the
 * other 1/2 from the texture border. It is sometimes desirable for a texture to be clamped to the border color, rather than to an average of the border
 * and edge colors.
 * 
 * This extension defines an additional texture clamping algorithm. {@link #GL_CLAMP_TO_BORDER_ARB CLAMP_TO_BORDER_ARB} clamps texture coordinates at all mipmap levels such that
 * {@link GL11#GL_NEAREST NEAREST} and {@link GL11#GL_LINEAR LINEAR} filters return only the color of the border texels.
 * 
 * Promoted to core in {@link GL13 OpenGL 1.3}.
