Subject: swrast: fix GL_ANY_SAMPLES_PASSED values in Result
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dcbf8377befde50fe4d75738e2af5813e06e8f04;p=mesa.git

swrast: fix GL_ANY_SAMPLES_PASSED values in Result

Since commit 922be4eab, the expectation is that the query result
contains the correct value. Unfortunately swrast does not distinguish
between GL_SAMPLES_PASSED and GL_ANY_SAMPLES_PASSED. As a result, we
must fix up the query result in a post-draw fixup.
