[Piglit] [PATCH] Allow testing of compressed texture formats with 1D textures

[Anuj Phogat]

OpenGL specification requires generic compressed texture formats to be
supported for 1D, 1D_ARRAY and TEXTURE_RECTANGLE targets.

Brian, after applying this patch I executed test case on NVIDIA drivers. It
fails for all texture formats with 1D textures. But test passes on i965 driver
for cases involving compressed texture formats and 1D textures. Although,
there are few unrelated 1D_ARRAY texture failures i965. I'll verify the output on
AMD as well.

NVIDIA driver I used for testing:
OpenGL renderer string: GeForce 210/PCIe/SSE2
OpenGL version string: 3.3.0 NVIDIA 295.53
OpenGL shading language version string: 3.30 NVIDIA via Cg compiler
