Subject: mesa/shaders: fix gl_NormalMatrix state parameters
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b928d18398330d862ab162f687e224b93932824c;p=mesa.git

mesa/shaders: fix gl_NormalMatrix state parameters

gl_NormalMatrix is the inverse transpose of the modelview matrix, but
as every matrix here needs to be transposed, we end up with
{MODELVIEW_MATRIX, INVERSE}.
