[Mesa-dev] [PATCH] st/mesa: use PIPE_USAGE_STREAM for GL_CLIENT_STORAGE_BIT

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

STAGING is mainly for fast CPU reads and random access. I don't think
glBufferStorage(GL_CLIENT_STORAGE_BIT) is used for those two purposes.
I'd say GL_CLIENT_STORAGE_BIT is more of a streaming-upload kind of thing.
