XFree86 4.5.99.22 (23 February 2006)
 221. cfb24 is no longer needed; don't link it into servers but still produce
      a loadable module for it.  Also, fix server make dependencies on Xserver/
      subdirectories (Marc La France).
 220. Fix incorrect bitsPerPixel for depth 12 in pixmap formats advertised by
      Xsun24 server (Marc La France).
 219. In linux/int10, produce messages when the mappings used to build up the
      BIOS's address space do not match expectations (Marc La France).
 218. Platforms-specific build/warning fixes (David Dawes).
 217. A rework of the way extension support is built into servers to allow for
      servers with different sets of extensions in the same build.  This starts
      with an idea introduced in David Dawes's TinyX work, and extends it to
      also apply to the Xprt, Xnest, Xvfb, Xdmx and Xsun* servers.  The changes
      include:
      - Add, as a comment, a definition for what makes an extension pervasive.
      - TOGCUP is not a pervasive extension, but XSYNC, BIGREQS and XRES are.
      - Consolidate #define's for the Xv, XvMC and XRES extensions.
      - Flip, in favour of the majority case, MITSHM's default decision WRT
        whether or not a framebuffer stores pixmap data in the server's virtual
        address space.  MI is now independent of MITSHM and MITSHM is no longer
        a pervasive extension.
      - Add a DIX helper to determine whether Xinerama is active and use it
        instead of #ifdef'ed code in all loadable modules.  Re-implement, as
        a screen wrapper, Xinerama's PaintWindow*() hacks.  Move down to DIX
        Xinerama's only MI hook.  Both MI and loadable module objects are now
        independent of Xinerama.
      - Add more XCSECURITY-related DIX helpers.  Loadable module objects that
        provide their own extensions (e.g. apm) are now independent of the core
        binary's support for XCSECURITY.
      - Extend DBE to allow for front and back buffer revalidations (to be used
        in future changes to restore the only existing example of DBE hardware
        acceleration after converting the sunffb driver to fb, XAA & Render).
        This is the change that chronologically started all this.
      - Separate Xv and XvMC extensions more cleanly.
      - Move Xserver/*/tiny directories under Xserver/hw/tinyx.
      - Fix !PrintOnlyServer builds.
      - Clean up Xserver/Imakefile.
      - Remove remaining traces of Xdec* servers.
      - Fix parallel make bug in Xserver/Imakefile caused by unintentional
        symbol re-use.
      - Accomodate XWin more cleanly by not "skipping" over Xserver/hw.
      - Remove all extension stub code (no longer needed).
      `make World` is required to correctly build these changes.  In fact, I
      recommend starting with a fresh checkout.  These changes are bundled as
      one commit due to module versioning considerations.  (Marc La France)
 216. Linux/alpha, Linux/amd64, Linux/ppc, Solaris/sparc build/warning fixes
      (David Dawes).
 215. Allow building with devel-specific system headers (David Dawes).
 214. Allow the privileged XFree86 server options to be used by a normal
      user when the server is not setuid/setgid (David Dawes).
 213. Add UseBuildTree config switch for development/debugging (David Dawes)
 212. Add getArgc and getArgv functions (David Dawes).
 211. Some Linux/alpha and Linux/ppc build/warning fixes (David Dawes).
 210. Build/config fixes (David Dawes).
 209. Change i740 to save & restore more of the mode on server entry
      (Marc La France).
 208. atimisc changes:  another DSP calculation tweak;  work-around for
      screen-to-screen copy corruption on second-generation integrated
      controllers;  make memory range prints faster (Marc La France).
 207. Xterm patch #209 (Thomas Dickey).
