/**
 * Native bindings to the ARB_texture_buffer_range extension.
 * 
 * {@link ARBTextureBufferObject ARB_texture_buffer_object} (which was promoted to core in OpenGL 3.1) introduced the ability to attach the data store of a buffer object to a buffer
 * texture and access it from shaders. The extension only allows the entire store of the buffer object to the texture. This extension expands on this and
 * allows a sub-range of the buffer's data store to be attached to a texture. This can be used, for example, to allow multiple buffer textures to be backed
 * by independent sub-ranges of the same buffer object, or for different sub-ranges of a single buffer object to be used for different purposes.
 * 
 * Requires {@link GL15 OpenGL 1.5}. Promoted to core in {@link GL43 OpenGL 4.3}.
