30/**
31 * CCMotionStreak manages a Ribbon based on it's motion in absolute space.
32 * You construct it with a fadeTime, minimum segment size, texture path, texture
33 * length and color. The fadeTime controls how long it takes each vertex in
34 * the streak to fade out, the minimum segment size it how many pixels the
35 * streak will move before adding a new ribbon segement, and the texture
36 * length is the how many pixels the texture is stretched across. The texture
37 * is vertically aligned along the streak segemnts.
38 *
39 * Limitations:
40 * CCMotionStreak, by default, will use the GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA blending function.
41 * This blending function might not be the correct one for certain textures.
42 * But you can change it by using:
43 * [obj setBlendFunc: (ccBlendfunc) {new_src_blend_func, new_dst_blend_func}];
44 *
45 * @since v0.8.1
