[Mesa-dev] [PATCH] mesa/main: handle double uniform matrices properly

[Samuel Iglesias Gonsálvez]

From: "Juan A. Suarez Romero" <jasuarez at igalia.com>

When computing the offset in the uniform storage table, take into account
the size multiplier so double precision matrices are handled correctly.
