Prim texture testing 20091014
I created a cube, hollowed it and cut it from both sides. Then placed textures on the sides and replicated each texture to be two times across and three times vertically.
The first two pictures are taken with the LL viewer. The latter two with LookingGlass. LookingGlass meshed the prim using the latest PrimMesher (fetched 20091013). Note that SL viewer shows the interior texture as one large, on-its-side image rather than as multiple faces.

Flipped Top testing 20091017
Here are two pictures taken of the same scene with different viewers. Notice the top of the cube closest. It's blue and the "4" texture is flipped. The cube just behind it has a "5" on it's bottom which is flipped. I believe the UV map on the top and bottom of cubes is upside down in PrimMesher.
