[cairo] trouble with Cairo text in OpenGL

[Bill Spitzak]

Does he need to do cairo_flush(cr) before using the pixels?

You did not set the current point before drawing the text, so I think it 
drew it at 0,0 and you are just seeing the descenders of some letters.

You may also need to do cairo_surface_flush(surface) before grabbing the 
image?
