tags - a pointer to tags to be used during creation.
CPS_GalliumInterfaceVersion - Indicates a version of gallium interface
that a client is expected to receive. The
client expected version must ideally match
with the version that the driver provides,
because gallium interface is not backwards
compatible. This tag is required. Unless
otherwise needed, the value
GALLIUM_INTERFACE_VERSION should be passed.

ignored.
The pipe screen is freed. Don't use it anymore.
