It worked for me.
I used 4 texels overlap, without the texture border GL extension
(I'm not sure if you were referring to it).
I didn't overlap the polygons, though, they shared the edge exactly.
The polygon edges were mapped to texels inside the texture image (4
texels away). You need to do this to avoid the edge artifacts of the
texture filter (or the repeat).
Bye,
