Oups! Where is this list?

Here is the output I got with
printf("bbs_mesh_solid (%d) %x\n", nb++, i);
and
printf("findnearestface %x\n", index);

I've separated the findnearestface in 4 blocks corresponding to clicks 
on the three visible faces I saw of the cube and in empty space for the 
last one.

As you can see, sample_backbuf does not return the colors used by the 
draw. Moreover the color is not constant through the same face. But it 
seems that the cube is correctly positionned since clicking outside 
correspond to color 0.
Is there a easy way to dump to a bitmap file the content of the backbuf 
to see how it has been drawn?
