[PATCH] render: return the supported version rather than just passing the proto's version

The spec says "the server sends the highest version it supports, but no
higher than the requested version".

This patch makes us send the highest version we support, rather than
whatever renderproto version was used when building the server.  Should
we start checking the client's version as well?  (the randr spec has the
same language, and the code just returns SERVER_RANDR_M{AJ,IN}OR)
