this was added for lavapipe, but it should have been in the framebuffer state since it is a framebuffer state now the GL multiview extensions are supported with viewmask in the framebuffer struct, which means this is all redundant and should be corrected/deleted Reviewed-by: Marek Olšák <marek.olsak@amd.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/31590>
