Subject: glsl ES: Fix magnitude of gl_MaxVertexUniformVectors.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8f51d68f8c2020ad35b442c4af693ad7a5e5dd0d;p=mesa.git

glsl ES: Fix magnitude of gl_MaxVertexUniformVectors.

Previously, we set it equal to MaxVertexUniformComponents.  It should
be MaxVertexUniformComponents / 4.

NOTE: This is a candidate for the stable branches.
