[Mesa-dev] [PATCH 3/4] mesa: Flag _NEW_ARRAY only if we are changing ctx->Array.VAO.

[Mathias.Froehlich at gmx.net]

From: Mathias Fröhlich <mathias.froehlich at web.de>

For the VAO internal helper functions that may be called
with a non current VAO, flag the _NEW_ARRAY state only
if it is the current ctx->Array.VAO.
