Include drawing primitives when using CCRenderTexture

Question

Following this: http://www.raywenderlich.com/4421/how-to-mask-a-sprite-with-cocos2d-1-0

And it works. However, for my needs I have to draw some cocos2d primitives in my sprite, and then, mask it.

So I made a subclass of CCSprite, and did this in the draw method:

-(void)draw {
    [super draw];
    glColor4f(1.0, 0.0, 0.0, 1.0);
    glLineWidth(2.0);
    ccDrawLine(ccp(0,0), ccp(480,320));
}

However, when I mask this sprite, the red line appears above everything (including the non-visible area).

I imagine I need a way to include my red line as part of the sprite's texture so that CCRenderTexture can properly take it all, but I'm not sure how.

Since the draw primitives methods are not use Z-order, I think you should draw the line to a seperated rendertexture, and then use the texture to do what you want to.
