如何让Cocos2dGameContainer和游戏内的canvas画面保持一致

如题如何让Cocos2dGameContainer和游戏内的canvas画面保持一致？就是1.10.2以前版本的效果。超出边界部分不显示。

最简单方法就是把camera画面投到RenderTexture内， 然后用sprite显示该RenderTexture， 然后加个Material与shader在游戏初始化时传入左＆右边界的世界坐标到material, 然后shader如下, 就是判断超出左右边范围时不渲染

CProgram vs %{
precision highp float;

#include <cc-global>

in vec3 a_position;

out vec4 v_color;
out vec3 v_position;

#if USE_TEXTURE
  in vec2 a_uv0;
  out vec2 v_uv0;
#endif

void main() {
  vec4 pos = vec4(a_position, 1);
  
  #if CC_USE_MODEL
    pos = cc_matViewProj * cc_matWorld * pos;
  #else
    pos = cc_matViewProj * pos;
  #endif
  
  #if USE_TEXTURE
    v_uv0 = a_uv0;
  #endif
  
  v_color = a_color;
  v_position = a_position;
  
  gl_Position = pos;
}
