[osg-users] Texture2DArray and invalid enumerant error

[Chris Kuliukas]

It'd be good to resolve this, I just spent half a day tracking this issue down. I eventually dug down to the error coming after glEnable(35866) was set, which is GL_TEXTURE_2D_ARRAY_EXT, and then coming to this.

If setTextureAttributeAndModes could just detect a Texture2DArray StateAttribute it could give a warning and save a lot of trouble.
