Subject: mesa: use geometric helper for computing min samples
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=beac7b1b8b0a74bbf0ef76e681a31c98e9250e55;p=mesa.git

mesa: use geometric helper for computing min samples

In case we have a draw buffer without attachments, we should be looking
at the default number of samples.
