/**

+ * casting it to a more specific extension and optionally advertising
+ * the GLX extension. See below for examples.
+ *
+ * We never break API in for a DRI extension. If we need to change
+ * the way things work in a non-backwards compatible manner, we
+ * introduce a new extension. During a transition period, we can
+ * leave both the old and the new extension in the driver, which
+ * allows us to move to the new interface without having to update the
+ * loader(s) in lock step.
+ *
+ * However, we can add entry points to an extension over time as long
+ * as we don't break the old ones. As we add entry points to an
+ * extension, we increase the version number. The corresponding
+ * #define can be used to guard code that accesses the new entry
+ * points at compile time and the version field in the extension

+ *
+ * DESCRIPTION
+ *
+ * This file contains a straightforward implementation of a fixed-sized
+ * hash table using self-organizing linked lists [Knuth73, pp. 398-399] for
+ * collision resolution. There are two potentially interesting things
+ * about this implementation:
+ *
+ * 1) The table is power-of-two sized. Prime sized tables are more
+ * traditional, but do not have a significant advantage over power-of-two
+ * sized table, especially when double hashing is not used for collision
+ * resolution.
+ *
+ * 2) The hash computation uses a table of random integers [Hanson97,
+ * pp. 39-41].
+ *
+ * FUTURE ENHANCEMENTS
+ *
+ * With a table size of 512, the current implementation is sufficient for a
+ * few hundred keys. Since this is well above the expected size of the
+ * tables for which this implementation was designed, the implementation of
+ * dynamic hash tables was postponed until the need arises. A common (and
+ * naive) approach to dynamic hash table implementation simply creates a
+ * new hash table when necessary, rehashes all the data into the new table,
+ * and destroys the old table. The approach in [Larson88] is superior in
+ * two ways: 1) only a portion of the table is expanded when needed,
+ * distributing the expansion cost over several insertions, and 2) portions
+ * of the table can be locked, enabling a scalable thread-safe
+ * implementation.
