Drivers that care about crtc positions on the screen to ensure that vblank
works correctly need to be notified when crtcs are changed.
Provide a hook in the mode setting code that is invoked whenever any
configuration is done to the screen.
Use this new hook in the DRI code so that DRI clients are notified and
receive updated information.

over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
The previous scheme didn't work when the client didn't create the core drawable,
e.g. the root or composite overlay window. Use refcounting via special client
resources to fix that.
The entity (device) has a locking SAREA and a master file descriptor
that optionally isn't closed between server generation.
The locking SAREA contains the device hardware lock.
Each DRI screen creates an new SAREA containing the drawable lock,
drawable-and private info, the drawable SAREA.
The first screen optionally shares its drawable SAREA with the
device SAREA.
Default is to close the master descriptor between server generations,
and to share the drawable SAREA of the first screen with the device locking
SAREA. Thus we should (hopefully) have full backwards compatibility.
Mesa changes to support single-device multiple screens are pending.
The hook is called whenever the clipList of any DRI window changes, be it via
DRIClipNotify, DRICreateDrawable or DRIDrawablePrivDelete. This allows the
driver to keep track of which DRI windows are visible where.
we only take it when clipping a DRI drawable instead of on every tree
update. Note drawable lock acquisition per- screen instead of globally,
and drop it in BlockHandler if necessary.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
