[Mesa-dev] [PATCH] swrast: fix GL_ANY_SAMPLES_PASSED values in Result

[Ilia Mirkin]

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.
