Subject: Don't perform dangling attribute check on POS attribute.  It can't by
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=87f602dd820b8cca5293bd30ba356123ab0f9e36;p=mesa.git

Don't perform dangling attribute check on POS attribute.  It can't by
definition dangle (every vertex has a position).  However
save->currentsz isn't properly maintained for this attribute, as there
is no current position value to track.  Reported by Haihao Xiang.
