-/** @file support for ARB_query_object
- *
- * ARB_query_object is implemented by using the PIPE_CONTROL command to stall
- * execution on the completion of previous depth tests, and write the
- * current PS_DEPTH_COUNT to a buffer object.
- *
- * We use before and after counts when drawing during a query so that
- * we don't pick up other clients' query data in ours. To reduce overhead,
- * a single BO is used to record the query data for all active queries at
- * once. This also gives us a simple bound on how much batchbuffer space is
- * required for handling queries, so that we can be sure that we won't
- * have to emit a batchbuffer without getting the ending PS_DEPTH_COUNT.
