Hello,

I'm trying to find out how to get a backbuffer for attached shader found in the 
web (http://glsl.heroku.com/e#8849.0), it seem I couldn't get alpha channel in 
gemframebuffer's recursion, any idea?

void main()
{
    gl_TexCoord[0] = gl_MultiTexCoord0;
    gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;

}
