glxinfo that queries the GLX_BIND_TO_MIPMAP_TEXTURE_EXT fbconfig attribute

In Clutter we are querying the GLX_BIND_TO_MIPMAP_TEXTURE_EXT fbconfig attribute to determine if we can using mipmapping + texture from pixmap. It seems with my Intel i965 driver this returns -1 for all fbconfigs. As I understand it, this should be a boolean value, and if I query the attribute with other drivers I get back either 0 or 1 for all fbconfigs.

Attached is a modified glxinfo that prints the value of the GLX_BIND_TO_MIPMAP_TEXTURE_EXT for all fbconfigs.

I tested with the attached glxinfo on gm45, and it all returns 0 both with EXA/UXA/UXA with xcompmgr.

So I'm closing this.

Bob, we are using Q4 rc2 package. If you still see this problem with the latest code, please reopen.
