- Merge various fb/ bits of COMPOSITE support from xserver, which weren't
necessary before due to cw hiding the issues. Fixes offset calculations
for a number of operations, and may pull some fixes that cairo has
wanted for XAA as well.
- Add a new call, miDisableCompositeWrapper(), which a DDX can call to keep
cw from getting initialized from the damage code. While it would be
cleaner to have each DDX initialize it if it needs it, we don't have
control over all of them (e.g. nvidia).
- Use the miDisableCompositeWrapper() to keep cw from getting set up for
screens using EXA, because EXA is already aware of composite. Avoiding
cw improved performance 0-35% on operations tested by ajax in x11perf.
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.
not at the backing pixmap's origin. Resulted in incorrect rendering in
at least aisleriot, fluxbox, and KDE apps, and probably many more.
While here, move the ParentRelative loop above the drawable grab -- may
improve correctness with ParentRelative background origins as well.
Note that the border code doesn't handle ParentRelative yet.
according to the rules as I understand them (bug #1045), not everybody
follows the rules. GC funcs were being called on the same GC from
within GC ops, and the cwValidateGC caused a loop in the funcs chain
that resulted in a crash, notably in cwPolylines.
to me.
Clean up transition between cheap and expensive GC wrappers by using the
prologue and epilogue macros. Before, the GC would be left unvalidated
sometimes which would cause all kinds of entertaining bugs against a
DDX which cares (XAA).
Eliminate needless (and, it turns out, dangerous) call to ChangeGC on
DestroyGCPrivate.
in cwSetWindowPixmap, check if the pixmap is the screen pixmap and disable
the wrapper by setting the private to NULL.
None works.
Copy filter to backing picture during validation.
Mark picture serialNumber when setting Filter or Transform so Validate
occurs.
Initialize xf86Screens[i]->pScreen to NULL so that RADEON driver doesn't
crash during server reset using old pScreen.
