 * A texture to be bound within JOGL. This object is responsible for

 * Since textures need to be powers of 2 the actual texture may be
 * considerably bigged that the source image and hence the texture
 * mapping coordinates need to be adjusted to matchup drawing the
 * sprite against the texture.
