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.
delivery of events to windows and clients.
This is tentative. It's likely that an additional last-resort hook will
be necessary for code that calls TryClientEvents or WriteEventsToClient
directly. It's also possible that new xace machinery will be necessary
to classify events and pull useful resource ID's out of them.
The failure case also needs some thinking through. Should event delivery
"succeed" or should it report undeliverable?
Finally, XKB appears to call WriteToClient to pass events. Sigh.
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.
This patch changes the semantics of manual redirect windows so that they no
longer affect the clip list of their parent. Doing this means the parent can
draw to the area covered by the child without using IncludeInferiors. More
importantly, this also means that the parent receives expose events when
that region is damaged by other actions.
arbitrary X status codes instead of just TRUE/FALSE.
The dix layer in most cases still does not propagate the return value of
XACE hooks back to the client, however. There is more error propagation
work to do.
Fix up prototypes for PrintChildren and PrintWindowTree in the dix.
Make miPrintRegion be unconditionally defined, and move the prototype into
regionstr.h.
Change a bunch of ScreenPtr pScreen = foo; to
ScreenPtr pScreen; pScreen = foo; in window.c, so we avoid unused variable
references (as inline REGION_* doesn't reference pScreen).
(Since all use is inside the xserver module, might as well keep the header
in the Xserver module instead of in proto/XExt to allow easier synchronization
of updates.)
Add new functions to enable and disable events on Map and Unmap.
Use them here to make sure Composite redirect doesn't cause Map/UnmapNotify
events that would confuse window managers.
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 "foo.h" to <X11/foo.h> for core headers, e.g. X.h, Xpoll.h;
change "foo.h", "extensions/foo.h" and "X11/foo.h" to
<X11/extensions/foo.h> for extension headers, e.g. Xv.h;
change "foo.[ch]" to <X11/Xtrans/foo.[ch]> for Xtrans files.

has several issues, including:
- CopyWindow and PaintWindow wrappers missing (will be done soon)
- Some segfaults seen in the Render wrappers.
- Xprt server build breaks with Composite.
- DDXs must be recompiled for Composite due to VisualRec size change.
- Composite bugs pointed out by Deron Johnson in email.
Also, reorder XFixes initialization according to comments by Keith which
are also in xserver CVS.
