[osg-users] Setting alpha channel in Frag Shader does not work.

So far the alpha channel is completely ignored beyond the shader. I set each vertex of the point cloud based off the r,g,b channels of the image buffer.

Before I add the vertex to the point cloud the r,g,b channels of the image already seem to be scaled. I check this by logging the image values.
