Subject: mesa: fix not having secondary color in ATI_fs in swrast
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a64d6fb7308e0ce79e0f1b8e9b7cda6403be1eb6;p=mesa.git

mesa: fix not having secondary color in ATI_fs in swrast

ATI_fs in swrast only had secondary color if GL_COLOR_SUM was enabled.
This patch probably fixes the same issue in r200.
