/* This test verifies the behaviour of cube maps wrt. texture wrapping.

* regardless of the actual addressing mode set. The way this test works is
* that we sample in one of the corners of the cubemap with filtering enabled,
* and check the interpolated color. There are essentially two reasonable
* things an implementation can do: Either pick one of the faces and
* interpolate the edge texel with itself (i.e., clamp within the face), or
* interpolate between the edge texels of the three involved faces. It should
* never involve the border color or the other side (texcoord wrapping) of a
* face in the interpolation. */
