From: Anuj Phogat <anuj.pho...@gmail.com> This is an updated patch to allow glTexImage2D with a depth component cube map. Patch was producing an expected ouput with depth-cube-map test (posted on piglit mailing list). But i'm getting an incorrect output since i updated my mesa branch with git://anongit.freedesktop.org/mesa/mesa. Luminance value is not getting copied to green and blue channels. So the color value i'm seeing in fragment shader is (L,0,0,1). I verified that this issue is only with depth cube maps not with depth 2D textures. Is this a known issue? I will try to debug it further.
