X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9e07a68cade6c75385cd52ca1f3e34d65a45fb31;p=mesa.git i965/Gen4-5: ensure VUE slots for clipdistance are valid if user clipping is enabled. V2: We don't particularly care where they fall in the VUE map, as long as they are allocated somewhere, and occupy two contiguous slots. Don't fiddle with the SF layout at all -- there's no need.
