This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
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.
Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
Create fbPrepareAccess macros to call into the driver to set up the
wfbReadMemory and wfbWriteWemory pointers. Call these from fbGetDrawable and
fbGetStipDrawable.
Add the READ and WRITE macros, which expand to simple memory accesses for fb,
and calls through the function pointers for wfb.
Add fbFinishAccess macro to give the driver an opportunity to clean up. Add
calls to this in the appropriate places.
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>.

- Change #ifdef for checking for old format miScreenInit to
FB_OLD_MISCREENINIT for easier portability to xservers with updated
screen structs but old function prototypes. Make it automatically
defined if FB_OLD_SCREEN is defined.
- Add _LP64 to list of #ifdefs for 64-bit platforms to support
64-bit Solaris.
